It implements the major formatting % requirements specified by the University, provides useful % macros to ease the process of building the title page and automatically % deals with fiddly little issues such as question and section numbering, % the number of pages in the paper, printing ``\textbf{TURN OVER}'' in the % bottom right corner of every page except the last one and ensuring that the % total number of marks for a question adds up to the expected number. % \end{abstract} % % % \tableofcontents % % % \section{Overview} % % \changes{2.1}{2004/04/10}{NJS Added requirements and installation instructions.} % \changes{2.3}{2012/09/04}{NJS Dropped vanilla \LaTeX\ for building docs.} % \subsection{Requirements and installation} % % The \textsf{ouexam} package requires the \textsf{verbatim}, % \textsf{fontenc}, \textsf{lmodern} and \textsf{textcomp} packages, all % of which should come standard with most \TeX\ installations. To build % the documentation and example files, you will need at least version 1.1 % of the \textsf{listings} package, and the \textsf{pdfjam} tool. % % Installation is relatively simple: % \begin{enumerate} % % \item Unpack the distribution archive and \texttt{cd} to the % distribution directory. % % \item \texttt{make}. % % \item \texttt{make install TEXMF\_INSTALL=/path/to/texmf}. % \texttt{/path/to/texmf} should be the root of your preferred % \texttt{texmf} tree (e.g., \texttt{/usr/share/texmf}). You may need % to do this as root depending on which \texttt{texmf} tree you are % installing into. You can also define \texttt{TEXMF\_INSTALL} as an % environment variable then simply type \texttt{make install}. % % \end{enumerate} % You can, of course, always install manually if you wish. % % % \changes{2.0}{2002/01/11}{NJS Added note on backwards compatibility.} % \subsection{Important note on backwards compatibility} % % Version 2.0 of \textsf{ouexam} introduced several major changes from earlier % versions. Consequently, documents created using an earlier version of % \textsf{ouexam} are \emph{incompatible} with version 2.0 or later. Versions 2.0 % and greater of \textsf{ouexam} will detect attempts to process a version 1.x % document and display an error message. % % The older version (1.2) is still available and can be downloaded from the same % location as the current version. To process older version documents, just copy % the version 1.2 |ouexam.cls| file into the same directory as the document file. % \TeX\ searches the current directory first, so this copy will take precedence % over any other installed version of \textsf{ouexam}. % % % \subsection{Class options} % % This document class is based on the \textsf{article} class and accepts % most of the options accepted by \textsf{article} (the \textsf{twoside}, % \textsf{10pt} and \textsf{11pt} options are ignored). The standard % options are \textsf{onecolumn}, \textsf{oneside}, \textsf{a4paper} and % \textsf{12pt}. In addition, \textsf{ouexam} accepts the following % ``native'' class options: % \begin{description} % \item[\textsf{draft}] \DescribeMacro{draft} This option has the usual % effects that you would expect for \textsf{draft} mode in the % \textsf{article} class, plus \fbox{DRAFT} is printed in % the footer of every page. Note that if you use the \textsf{graphicx} % package and turn on the \textsf{draft} option in \textsf{ouexam}, all % included graphics will be drawn in draft mode unless you specify the % |draft=false| option to \cs{includegraphics}. % % \item[\textsf{markingschedule}] \DescribeMacro{markingschedule} % Rather than write a separate marking schedule for an examination paper, you % can use the \textsf{marking} environment to embed marking information % within questions (see % \hyperref[Sec:Questions:Marking]{section~\ref*{Sec:Questions:Marking}}). % By default this information is not printed (for obvious reasons!), but % when it comes time to print a marking schedule for the examination, % including the \textsf{markingschedule} class option in the % \cs{usepackage} command will cause \textsf{ouexam} to print the hidden % content. It will also print \fbox{MARKING SCHEDULE} in the header of % every page. % % \item[\textsf{times}] \DescribeMacro{times} % The Examinations Office prefers all examination papers to be set in 12pt % Palatino. However, if this is not available, they will accept 13pt Times % instead. The \textsf{times} class option enables the latter, but should % only be used if Palatino is not available. % \end{description} % % % \subsection{Required packages} % % This class requires the \textsf{verbatim} package in order to implement % the marking schedule functionality. It also expects modern \LaTeX\ font % handling capabilities, and therefore requires the \textsf{fontenc}, % \textsf{textcomp} and \textsf{lmodern} classes. % % % \subsection{Page margins} % % This class assumes A4 paper. You will probably get weird results if you try % to do anything different. The margins are set up as follows: top and bottom % 2cm (headers and footers are inside this margin), left and right 2.54cm (1in). % % % \changes{2.1.1}{2006/08/21}{NJS Updated \textsf{lastpage} style to display % ``\textbf{END}''.} % \subsection{Page styles} % % There are two page styles defined in this class: % \begin{description} % \item[\textsf{plain}] \DescribeMacro{plain} This is a slight modification of the \textsf{plain} page style from \textsf{article}. It produces pages that have the page number centered at the bottom, the paper number in the top right corner and the text ``\textbf{TURN OVER}'' in the bottom right of every page except the last page, which has ``\textbf{END}'' instead. This is the default page style. % % \item[\textsf{titlepage}] \DescribeMacro{titlepage} This is similar to \textsf{plain} but without the page header, and is used for the title page of the paper. You will normally not use this yourself, because the \cs{maketitlepage} macro handles this automatically (see \hyperref[Sec:TitlePage]{section~\ref*{Sec:TitlePage}}). % \end{description} % % % \section{Writing an examination paper} % % % \changes{2.0.2}{2002/05/11}{NJS Moved the title page subsection to the start % of this section.} % \subsection{The title page} % \label{Sec:TitlePage} % % This class defines a collection of macros that let you fill in the various % parts of the examination title page. This is analogous to the process you use % to generate the title of a document in, for example, the \textsf{article} class % (using \cs{title}, \cs{author}, \cs{date} and \cs{maketitle}). That is, you % issue the macros described below in the document preamble, then issue a % \cs{maketitlepage} in the document body. % % The \DescribeMacro{\examyear} \cs{examyear} macro lets you specify the year % in which the examination is being held, for example, |\examyear{1999}|. This % macro is mandatory. % % The \DescribeMacro{\department} \cs{department} macro lets you specify the % name of the department that produced the examination paper, for example, % |\department{Information| |Science}|. This macro is mandatory. % % The \DescribeMacro{\papernumber} \cs{papernumber} macro lets you specify % the paper number that the examination is for, for example, % |\papernumber{COMP 101}|. This macro is mandatory. Note that when you % specify semester information using \cs{semester}, this is appended to % the paper number in the page header. For example, if you specify % |\papernumber{COMP 101}| and |\semester{2}|, the header will contain % ``COMP 101 (Semester Two)'' rather than just ``COMP 101''. % % The \DescribeMacro{\papertitle} \cs{papertitle} macro lets you specify the % title of the paper, for example, % |\papertitle{Systems Analysis and Design Methods}|. This macro is mandatory. % % \changes{2.0.2}{2002/08/22}{NJS Added `FY' to the \cs{semester} macro % description.} % Some papers are offered in more than one semester. The % \DescribeMacro{\semester} \cs{semester} macro lets you specify which % semester the examination is for. The argument can be either ``1'' or ``2'' % for semesters 1 and 2, ``SS'' for summer school, ``FY'' for a full-year % paper or ``SP'' for a special examination, for example, |\semester{2}|. % Invalid values for the argument cause a warning to be raised. This macro is % optional---if you omit it, no semester information is generated. % % The \DescribeMacro{\timeallowed} \cs{timeallowed} macro lets you specify the % length of the examination in hours, for example, |\timeallowed{2}|. This % macro is optional---if you omit it, it defaults to three (3) hours. % % \changes{2.1}{2004/04/05}{NJS Modified \cs{allowcalculators} to conform % to the new University calculator regulations.} % \changes{2.1}{2004/04/05}{NJS Added \cs{permitcalculators} as a synonym % for \cs{allowcalculators}.} % If calculators are permitted in the examination, use the % \DescribeMacro{\allowcalculators} % \DescribeMacro{\permitcalculators} % \cs{allowcalculators} macro (\cs{permitcalculators} will also work). % This macro is optional---if you omit it, a sentence is inserted saying % that calculators are \emph{not} permitted. \cs{allowcalculators} has a % single optional argument that specifies the kind of calculators % permitted. If omitted, it defaults to ``any'' (see below). Otherwise, % this argument must be one of the following values: % \begin{description} % % \item[\textsf{none}] A sentence is inserted noting that no calculators are % permitted. % % \item[\textsf{approved}] A sentence is inserted noting that only approved % calculators are permitted. % % \item[\textsf{any}] (default) A sentence is inserted noting that any % calculator that does not have a communication capability is % permitted. % % \end{description} % % The \DescribeMacro{\instructions} \cs{instructions} macro lets you specify % instructions on how candidates should complete the % examination, for example, |\instructions{Answer ALL| |questions.}|. This macro % is optional. Note that the content of the instructions can be just about % anything. It is up to you to control formatting, such as how you want lines % broken, etc. This also true of the \cs{material}, \cs{copiesof} and % \cs{otherinstructions} macros described below. % % The \DescribeMacro{\material} \cs{material} macro lets you specify any % additional material that candidates are provided in addition to the % examination paper itself, for example, |\material{SQL schema definition}|. % This macro is optional. % % The \DescribeMacro{\copiesof} \cs{copiesof} macro lets you specify any % material that candidates are allowed to bring into the examination, for % example, |\copiesof{McFadden &| |Hoffer, 5th edition}|. This macro is % optional. % % The \DescribeMacro{\otherinstructions} \cs{otherinstructions} macro lets you % specify any other instructions not covered by any of the above, for example, % |\otherinstructions{No smoking| |allowed.}|. This macro is optional. % % Once you have specified the content of the title page using the above % macros, you simply issue a \DescribeMacro{\maketitlepage} \cs{maketitlepage} % to generate the front page of the examination (cf. \cs{maketitle}). The title % page generated meets University formatting requirements. % Note that the number of pages in the examination paper is generated % and inserted into the title page automatically---you do not need to specify % it manually. % % % \subsection{Sections} % \label{Sec:Sections} % % Examination papers may optionally have multiple sections, ``numbered'' A, B, etc. Rather than redefine the existing \LaTeX\ section macros, \textsf{ouexam} defines an \DescribeEnv{examsection} \textsf{examsection} environment that generates a new section. The \textsf{examsection} environment has three mandatory arguments: % \begin{enumerate} % \item The expected number of marks for the question. If you leave this argument empty it defaults to zero. By default, \textsf{ouexam} keeps a running total of the \emph{actual} number of marks encountered within a section, which is compared with the value of this argument when the environment is closed (use the |ignoresubtotals| option to disable this, see below). An error is raised if the values are not equal. The running total is also typeset right-justified at the end of the section in the form ``\textbf{[SECTION A TOTAL 20 MARKS]}'' (unless the |hidetotal| option is specified, see below) as an additional verification (or just ``\textbf{[TOTAL 20 MARKS]}'' if the |hidetitle| option is specifed, see below). % % \item Instructions for answering questions in this section, such as ``\textbf{ANSWER ANY \underline{TWO} QUESTIONS.}''. The argument will be typeset in \textbf{bold face}. If you leave this argument empty it defaults to ``\textbf{ANSWER \underline{ALL} QUESTIONS (TOTAL xx MARKS).}'' (the marks total is omitted if it is zero or if the |hidetotal| option is specified, see below). % % \item A description of the topic of the section (this could also be used to provide further, more detailed instructions). This can be left empty. % \end{enumerate} % % The optional argument to \textsf{examsection} is a list of option keywords that control its behaviour. The available keys are: % \begin{description} % \item[\texttt{showtitle}] Print the title of the section (enabled by default). Use |hidetitle| to suppress this. % % \item[\texttt{showtotal}] Print a summary at the end of the section of the number of marks in the section (enabled by default). Use |hidetotal| to suppress this. This key does not cascade to any questions within the section. % % \item[\texttt{checksubtotals}] Calculate the running total of marks for questions within the section, and verify that this matches the expected number of marks. Use |ignoresubtotals| to suppress this (this also implies |hidetotal|). % \end{description} % % Every section begins on a new page, and the section title is formatted as ``\textbf{\underline{Section A}}'', in \cs{large} size, unless the |hidetitle| option is specified. For example: \\ % % \noindent|\begin{examsection}{25}{}{These questions are remarkably boring.}| \\ % \hspace*{1cm}\vdots \\ % |\end{examsection}| \\ % % \noindent will produce the following (assuming that the actual number of % marks in the question is correct): % % \begin{center} % \fbox{% % \begin{minipage}{0.9\columnwidth} % {\large\noindent\textbf{\underline{Section~A}}} \\[0.5\baselineskip] % \textbf{ANSWER \underline{ALL} QUESTIONS (TOTAL 25 MARKS).} \\ % These questions are remarkably boring. \\ % \hspace*{2cm}\vdots \\ % \mbox{}\hfill\textbf{[SECTION A TOTAL 25 MARKS]} % \end{minipage} % } % \end{center} % % \noindent whereas if we specify |hidetitle|: % % \begin{center} % \fbox{% % \begin{minipage}{0.9\columnwidth} % \textbf{ANSWER \underline{ALL} QUESTIONS (TOTAL 25 MARKS).} \\ % These questions are remarkably boring. \\ % \hspace*{2cm}\vdots \\ % \mbox{}\hfill\textbf{[TOTAL 25 MARKS]} % \end{minipage} % } % \end{center} % % % \subsection{Questions} % \label{Sec:Questions} % % \textsf{ouexam} provides three environments for building examination % questions: \DescribeEnv{question} \textsf{question}, % \DescribeEnv{subquestion} \textsf{subquestion} and \textsf{subsubquestion}, % which correspond to top-level questions, parts of questions, and % \DescribeEnv{subsubquestion} sub-parts of questions respectively. They % produce questions that are numbered according to University examination % formatting requirements. Note that questions are normally numbered % sequentially throughout the entire paper regardless of any section % boundaries. % % All three environments have a single mandatory argument which is the % expected number of marks for the question, part or sub-part. If this % argument is left empty it will default to zero (this has the side effect of % not printing the marks total at the end of the question). This argument works % in much the same way as the first argument to the \textsf{examsection} % environment (see \hyperref[Sec:Sections]{section~\ref*{Sec:Sections}}): % \textsf{ouexam} keeps a running total of the number of marks encountered % within each question part and sub-part, and compares this total with the % expected value when the environment closes. Where appropriate, the running % total is typeset right-justified in the form ``(5 marks)''. For example: % \begin{verbatim} % \begin{question}{5} % \begin{subquestion}{2} % Why is the sky blue? % \end{subquestion} % \begin{subquestion}{3} % Explain in detail how the sky can be made pink. % \end{subquestion} % \end{question} % \begin{question}{1} % Define the term ``floccinaucinihilipilification''. % \end{question} % \end{verbatim} % % \noindent will produce the following: % \begin{center} % \fbox{% % \begin{minipage}{0.9\columnwidth} % \begin{enumerate} % \item % \begin{enumerate} % \item Why is the sky blue? \hfill (2 marks) % % \item Explain in detail how the sky can be made pink. \hfill (3 % marks) % \end{enumerate} % % \item Define the term ``floccinaucinihilipilification''. \hfill (1 % mark) % \end{enumerate} % \end{minipage} % } % \end{center} % % The \textsf{question} environments handle formatting of marks totals % automatically, including considerations such as: % \begin{itemize} % \item whether or not to print the number of marks for a question at all % (they should not be printed if the question has sub-parts, and will also % not be printed if the number of marks is zero); % % \item whether to print ``mark'' or ``marks'' (e.g., question 2 above); and % % \item where to position the number of marks relative to the question, % depending on how full the last line of the question is. % \end{itemize} % % \changes{2.4}{2013/05/31}{NJS Enforced proper question environment nesting.} % The various \textsf{question} environments must be correctly nested in order for the features described above to work correctly, i.e., \textsf{question} at the top level, followed by \textsf{subquestion} and \textsf{subsubquestion}. Any variation to this nesting order will cause an error. % % \changes{2.4}{2013/06/13}{NJS Added \cs{questionskip} to control spacing between questions.} % You can control the spacing between top-level questions by redefining the \DescribeMacro{\questionskip} \cs{questionskip} length. It defaults to \cs{baselineskip}. Note that this applies only to the \textsf{question} environment; there are no equivalent lengths for \textsf{subquestion} or \textsf{subsubquestion}. % % % \changes{2.2}{2010/04/26}{NJS Added time allocation macros.} % \subsection{Time allocations} % \label{Sec-Questions-Time} % % If you wish to suggest a time allocation for completing a question, use the \DescribeMacro{\timeallocation} \cs{timeallocation} macro. The only argument is the number of minutes to be allocated for this question. The macro will output the time allocation in the form: \textbf{[The suggested time allocation for this question is \emph{t} minutes.]} % % If you wish to allow a certain amount of time for candidates to read some text, use the \DescribeMacro{\readingtime} \cs{readingtime} macro. The only argument is the number of minutes to be allocated for reading time. The macro will output the reading time in the form: \textbf{[Allow \emph{t} minutes reading time.]} % % Both macros assume the base unit to be minutes; if you wish to change this you will need to redefine the macros. Otherwise, the argument can be almost anything: text, numbers, etc. % % \textsf{ouexam} currently does not check that time allocations sum correctly. This may be implemented in a future version. % % % \subsection{Marking schedule information} % \label{Sec:Questions:Marking} % % Rather than writing a separate marking schedule for an examination paper, % you can use the \DescribeEnv{marking} \textsf{marking} environment to embed % marking information within questions. By default this information is not % printed (for obvious reasons!), but when it comes time to print a marking % schedule for the examination, use the \textsf{markingschedule} class option % to print the hidden content. The marking information will be set in % \emph{italics} to differentiate it from the main body of the examination, % and \fbox{MARKING SCHEDULE} will also be printed in the header of every % page. % % \changes{2.1}{2004/04/10}{NJS Added driver file tip.} % A useful tip for writing examination papers is to create two separate % ``driver'' documents that are set up the document class for the % ``plain'' and ``marking schedule'' versions of the examination, % respectively. Each should then include a separate document that contains % the actual content of the examination paper, for example: % % \begin{verbatim} % \documentclass[markingschedule]{ouexam} % % \input{exampaper} % contains the actual examination content % \end{verbatim} % % Doing this enables you to build the ``plain'' and ``marking schedule'' % versions independently, without overwriting each other or having to % change the original source file. Simply run \LaTeX\ on the appropriate % driver file to produce the version that you want. See the example files % that came with the \textsf{ouexam} distribution for an example of this % approach in action. % % % \subsection{Miscellaneous} % % Most examinations are marked out of 100, and \textsf{ouexam} defaults to % this. However, if you want an examination that is marked out of some other % number, for example, 90 marks, you can specify this using the % \DescribeMacro{\examoutof} \cs{examoutof} macro. Thus, |\examoutof{90}| % will set the expected number of marks for the examination to 90. This value % is used by \textsf{ouexam} to verify that the marks for all the questions % add up to the expected number of marks for the examination. % % % \section{Errors and warnings} % % In this section are described the error messages and warning produced by % \textsf{ouexam}, and the reasons why they occur. % % % \subsection{Error messages} % % \noindent\texttt{OBSOLETE (\ldots): this document was written for an % earlier} \\ % \texttt{version of ouexam \ldots} \\ % You are trying to use v2.0 or later of \textsf{ouexam} with a document that was written for \textsf{ouexam} v1.2 or earlier. Versions 2.0 and later of \textsf{ouexam} are \emph{fundamentally incompatible} with earlier versions. The only solutions here are either to revert to \textsf{ouexam} v1.2 or earlier (you can put a copy of the class file in the same directory as the document), or rewrite the document to conform to the current version of \textsf{ouexam}.

Group~1 % queries only inactive customers, group~2 queries only bronze status % customers and groups~3 and~4 both query only silver and gold status % customers. Members of any group may query the table at any time and % queries often overlap. % % \item UPDATE, INSERT and DELETE operations on the table are uncommon. % % \item Very few queries are for individual customers; rather, most % queries are based on various combinations of values from % \textsf{status}, \textsf{city}, \textsf{state} and \textsf{country}. % \end{itemize}\medskip % % \begin{subquestion}{3} % Describe and justify an \emph{index-based} physical tuning solution % that will improve the performance of queries on the \textsf{Customer} % table. (No code is required.) % \begin{marking} % Since queries tend to be on combinations of several low-cardinality % columns [1] and the table is very large [1], the most effective % solution would be to place bitmap indexes on status, city, state and % country [1]. % % B-tree indexes on any of the individual columns would not be ideal % because of their low cardinality. A possible alternative is a % composite B-tree index on all four columns [1 for suggesting this if % appropriate], but this is not ideal and would be much larger than % the four bitmap indexes [1 for this explanation if appropriate]. % Hashing is definitely \emph{not} an option, because very few queries % are exact match. % \end{marking} % \end{subquestion} % % \begin{subquestion}{7} % \begin{subsubquestion}{5}\label{nonindex} % Assuming that there are two identical fast disks available, describe % and justify two alternative \emph{non index-based} physical tuning % solutions that will improve the performance of queries on the % \textsf{Customer} table. For each solution include details of how % the two disks will be used. (No code is required.) % \begin{marking} % Alternative 1: partition the table across the two disks based on % status (four partitions, one for each status value) [1]. This will % allow simultaneous parallel access to different parts of the table % by the different groups [1]. Since two groups both access silver % and gold customers, it makes sense to put the silver customers on % disk one and the gold customers on disk two. Bronze customers % account for 50\% of the table, so it makes sense to also put them % on disk two (as the gold customers are the smallest group), and % put the inactive customers on disk one with the silver customers. % [1 for any sensible partitioning scheme] % % Alternative 2: replicate the table across both disks (one replica % on each disk) [1]. This will also provide simultaneous parallel % access to the data (hard to tell whether this would be better or % worse than the partitioning above) [1]. % % Note that any solution must be capable of being implemented in % Oracle8. % \end{marking} % \end{subsubquestion} % % \begin{subsubquestion}{2} % Briefly discuss the relative advantages and/or disadvantages of the % two alternative solutions you described in part~(\ref{nonindex}) % above. % \begin{marking} % The partitioning solution given above doesn't really help with the % bronze customer rows---we would need random horizontal % partitioning to really help with this, which Oracle8 doesn't % support. More generally, Oracle8 does not migrate rows into the % correct partition if a customer's status changes, so the data will % need to be reloaded occasionally [1]. % % For replication, we have the usual problem of keeping the replicas % synchronised if they are both read/write. This is somewhat % mitigated by the fact that there are only two copies [1]. % \end{marking} % \end{subsubquestion} % \end{subquestion} % \end{question} % % \newpage % \begin{question}{10} % There are two generic parameters that affect the structure of a B-tree % index. % % \begin{subquestion}{6} % Identify these two parameters and describe what each parameter % specifies.

These are placed on one or more automatically-generated float pages at the end, which \cs{pagestyle} and \cs{thispagestyle} don't affect. That is, a \textsf{lastpage} page style simply doesn't work in this situation. % % The solution is therefore to not use a page style, but rather check in the \textsf{plain} page style whether or not this is the last page, because the page style macro will be expanded for every float page that is generated. Again, this isn't as simple as it sounds! The logic goes like this: % % \begin{itemize} % % \item If there are no unprocessed floats, meaning that the last page of the document will be a text page (indicated by \cs{@lastpagetexttrue}), then output ``\textbf{END}''. % % \item If there are unprocessed floats, meaning that the last page of the document will be a float page (indicated by \cs{@lastpagefloattrue}), then: % % \begin{itemize} % % \item If a float page is currently being generated (indicated by \cs{@fcolmadetrue} from \texttt{latex.ltx}), then: % % \begin{itemize} % % \item If there are no more unprocessed floats (\cs{@deferlist} is empty), output ``\textbf{END}''. % % \item Otherwise, output ``\textbf{TURN OVER}''. % % \end{itemize} % % \item Otherwise, output ``\textbf{TURN OVER}''. % % \end{itemize} % % \item Otherwise, output ``\textbf{TURN OVER}''. % % \end{itemize} % \begin{macrocode} \if@lastpagetext END% \else\if@lastpagefloat\if@fcolmade\ifx\@deferlist\@empty END% \else TURN OVER\fi% \else TURN OVER\fi% \else TURN OVER\fi% \fi}}}% }% \let\@evenfoot\@oddfoot% } % \end{macrocode} % \end{macro} % % \textsf{plain} is the default page style: % % \begin{macrocode} \pagestyle{plain} % \end{macrocode} % % \cs{AtEndDocument}, we need to set the \texttt{lastpage} switches accordingly. The \cs{@deferlist} macro from \texttt{latex.ltx} holds a list of any unprocessed floats, so if this is empty, we know that there's nothing more to do and can just set \cs{@lastpagetexttrue}. If the list still contains unprocessed floats, set \cs{@lastpagefloattrue} then \cs{clearpage} to force the floats out. We also need to decrement the page counter by one, otherwise it ends up being one too many, which is presumably a side effect of the explicit \cs{clearpage}. % \begin{macrocode} \AtEndDocument{% \ifx\@deferlist\@empty% \@lastpagetexttrue% \else% \@lastpagefloattrue% \clearpage% \addtocounter{page}{-1}% \fi% } % \end{macrocode} % % \begin{macro}{\ps@titlepage} % The \textsf{titlepage} page style is similar to \textsf{plain}, but without the header. % \begin{macrocode} \def\ps@titlepage{% \def\@oddhead{\@markingschedule}% \let\@evenhead\@oddhead% \def\@oddfoot{\@draft\hfill\textbf{TURN OVER}}% \let\@evenfoot\@oddfoot% } % \end{macrocode} % \end{macro} % % % \subsection{Various counters} % % Earlier versions of \textsf{ouexam} used the \textsf{enumerate} % environment to build questions, which meant that special counters were not % required.

You can also define \texttt{TEXMF\_INSTALL} as an % environment variable then simply type \texttt{make install}. % % \end{enumerate} % You can, of course, always install manually if you wish. % % % \changes{2.0}{2002/01/11}{NJS Added note on backwards compatibility.} % \subsection{Important note on backwards compatibility} % % Version 2.0 of \textsf{ouexam} introduced several major changes from earlier % versions. Consequently, documents created using an earlier version of % \textsf{ouexam} are \emph{incompatible} with version 2.0 or later. Versions 2.0 % and greater of \textsf{ouexam} will detect attempts to process a version 1.x % document and display an error message. % % The older version (1.2) is still available and can be downloaded from the same % location as the current version. To process older version documents, just copy % the version 1.2 |ouexam.cls| file into the same directory as the document file. % \TeX\ searches the current directory first, so this copy will take precedence % over any other installed version of \textsf{ouexam}. % % % \subsection{Class options} % % This document class is based on the \textsf{article} class and accepts % most of the options accepted by \textsf{article} (the \textsf{twoside}, % \textsf{10pt} and \textsf{11pt} options are ignored). The standard % options are \textsf{onecolumn}, \textsf{oneside}, \textsf{a4paper} and % \textsf{12pt}. In addition, \textsf{ouexam} accepts the following % ``native'' class options: % \begin{description} % \item[\textsf{draft}] \DescribeMacro{draft} This option has the usual % effects that you would expect for \textsf{draft} mode in the % \textsf{article} class, plus \fbox{DRAFT} is printed in % the footer of every page. Note that if you use the \textsf{graphicx} % package and turn on the \textsf{draft} option in \textsf{ouexam}, all % included graphics will be drawn in draft mode unless you specify the % |draft=false| option to \cs{includegraphics}. % % \item[\textsf{markingschedule}] \DescribeMacro{markingschedule} % Rather than write a separate marking schedule for an examination paper, you % can use the \textsf{marking} environment to embed marking information % within questions (see % \hyperref[Sec:Questions:Marking]{section~\ref*{Sec:Questions:Marking}}). % By default this information is not printed (for obvious reasons!), but % when it comes time to print a marking schedule for the examination, % including the \textsf{markingschedule} class option in the % \cs{usepackage} command will cause \textsf{ouexam} to print the hidden % content. It will also print \fbox{MARKING SCHEDULE} in the header of % every page. % % \item[\textsf{times}] \DescribeMacro{times} % The Examinations Office prefers all examination papers to be set in 12pt % Palatino. However, if this is not available, they will accept 13pt Times % instead. The \textsf{times} class option enables the latter, but should % only be used if Palatino is not available. % \end{description} % % % \subsection{Required packages} % % This class requires the \textsf{verbatim} package in order to implement % the marking schedule functionality. It also expects modern \LaTeX\ font % handling capabilities, and therefore requires the \textsf{fontenc}, % \textsf{textcomp} and \textsf{lmodern} classes. % % % \subsection{Page margins} % % This class assumes A4 paper. You will probably get weird results if you try % to do anything different. The margins are set up as follows: top and bottom % 2cm (headers and footers are inside this margin), left and right 2.54cm (1in). % % % \changes{2.1.1}{2006/08/21}{NJS Updated \textsf{lastpage} style to display % ``\textbf{END}''.} % \subsection{Page styles} % % There are two page styles defined in this class: % \begin{description} % \item[\textsf{plain}] \DescribeMacro{plain} This is a slight modification of the \textsf{plain} page style from \textsf{article}. It produces pages that have the page number centered at the bottom, the paper number in the top right corner and the text ``\textbf{TURN OVER}'' in the bottom right of every page except the last page, which has ``\textbf{END}'' instead. This is the default page style. % % \item[\textsf{titlepage}] \DescribeMacro{titlepage} This is similar to \textsf{plain} but without the page header, and is used for the title page of the paper. You will normally not use this yourself, because the \cs{maketitlepage} macro handles this automatically (see \hyperref[Sec:TitlePage]{section~\ref*{Sec:TitlePage}}). % \end{description} % % % \section{Writing an examination paper} % % % \changes{2.0.2}{2002/05/11}{NJS Moved the title page subsection to the start % of this section.} % \subsection{The title page} % \label{Sec:TitlePage} % % This class defines a collection of macros that let you fill in the various % parts of the examination title page. This is analogous to the process you use % to generate the title of a document in, for example, the \textsf{article} class % (using \cs{title}, \cs{author}, \cs{date} and \cs{maketitle}). That is, you % issue the macros described below in the document preamble, then issue a % \cs{maketitlepage} in the document body. % % The \DescribeMacro{\examyear} \cs{examyear} macro lets you specify the year % in which the examination is being held, for example, |\examyear{1999}|. This % macro is mandatory. % % The \DescribeMacro{\department} \cs{department} macro lets you specify the % name of the department that produced the examination paper, for example, % |\department{Information| |Science}|. This macro is mandatory. % % The \DescribeMacro{\papernumber} \cs{papernumber} macro lets you specify % the paper number that the examination is for, for example, % |\papernumber{COMP 101}|. This macro is mandatory. Note that when you % specify semester information using \cs{semester}, this is appended to % the paper number in the page header. For example, if you specify % |\papernumber{COMP 101}| and |\semester{2}|, the header will contain % ``COMP 101 (Semester Two)'' rather than just ``COMP 101''. % % The \DescribeMacro{\papertitle} \cs{papertitle} macro lets you specify the % title of the paper, for example, % |\papertitle{Systems Analysis and Design Methods}|. This macro is mandatory. % % \changes{2.0.2}{2002/08/22}{NJS Added `FY' to the \cs{semester} macro % description.} % Some papers are offered in more than one semester. The % \DescribeMacro{\semester} \cs{semester} macro lets you specify which % semester the examination is for. The argument can be either ``1'' or ``2'' % for semesters 1 and 2, ``SS'' for summer school, ``FY'' for a full-year % paper or ``SP'' for a special examination, for example, |\semester{2}|. % Invalid values for the argument cause a warning to be raised. This macro is % optional---if you omit it, no semester information is generated. % % The \DescribeMacro{\timeallowed} \cs{timeallowed} macro lets you specify the % length of the examination in hours, for example, |\timeallowed{2}|. This % macro is optional---if you omit it, it defaults to three (3) hours. % % \changes{2.1}{2004/04/05}{NJS Modified \cs{allowcalculators} to conform % to the new University calculator regulations.} % \changes{2.1}{2004/04/05}{NJS Added \cs{permitcalculators} as a synonym % for \cs{allowcalculators}.} % If calculators are permitted in the examination, use the % \DescribeMacro{\allowcalculators} % \DescribeMacro{\permitcalculators} % \cs{allowcalculators} macro (\cs{permitcalculators} will also work). % This macro is optional---if you omit it, a sentence is inserted saying % that calculators are \emph{not} permitted. \cs{allowcalculators} has a % single optional argument that specifies the kind of calculators % permitted. If omitted, it defaults to ``any'' (see below). Otherwise, % this argument must be one of the following values: % \begin{description} % % \item[\textsf{none}] A sentence is inserted noting that no calculators are % permitted. % % \item[\textsf{approved}] A sentence is inserted noting that only approved % calculators are permitted. % % \item[\textsf{any}] (default) A sentence is inserted noting that any % calculator that does not have a communication capability is % permitted. % % \end{description} % % The \DescribeMacro{\instructions} \cs{instructions} macro lets you specify % instructions on how candidates should complete the % examination, for example, |\instructions{Answer ALL| |questions.}|. This macro % is optional. Note that the content of the instructions can be just about % anything. It is up to you to control formatting, such as how you want lines % broken, etc. This also true of the \cs{material}, \cs{copiesof} and % \cs{otherinstructions} macros described below. % % The \DescribeMacro{\material} \cs{material} macro lets you specify any % additional material that candidates are provided in addition to the % examination paper itself, for example, |\material{SQL schema definition}|. % This macro is optional. % % The \DescribeMacro{\copiesof} \cs{copiesof} macro lets you specify any % material that candidates are allowed to bring into the examination, for % example, |\copiesof{McFadden &| |Hoffer, 5th edition}|. This macro is % optional. % % The \DescribeMacro{\otherinstructions} \cs{otherinstructions} macro lets you % specify any other instructions not covered by any of the above, for example, % |\otherinstructions{No smoking| |allowed.}|. This macro is optional. % % Once you have specified the content of the title page using the above % macros, you simply issue a \DescribeMacro{\maketitlepage} \cs{maketitlepage} % to generate the front page of the examination (cf. \cs{maketitle}). The title % page generated meets University formatting requirements. % Note that the number of pages in the examination paper is generated % and inserted into the title page automatically---you do not need to specify % it manually. % % % \subsection{Sections} % \label{Sec:Sections} % % Examination papers may optionally have multiple sections, ``numbered'' A, B, etc. Rather than redefine the existing \LaTeX\ section macros, \textsf{ouexam} defines an \DescribeEnv{examsection} \textsf{examsection} environment that generates a new section. The \textsf{examsection} environment has three mandatory arguments: % \begin{enumerate} % \item The expected number of marks for the question. If you leave this argument empty it defaults to zero. By default, \textsf{ouexam} keeps a running total of the \emph{actual} number of marks encountered within a section, which is compared with the value of this argument when the environment is closed (use the |ignoresubtotals| option to disable this, see below). An error is raised if the values are not equal. The running total is also typeset right-justified at the end of the section in the form ``\textbf{[SECTION A TOTAL 20 MARKS]}'' (unless the |hidetotal| option is specified, see below) as an additional verification (or just ``\textbf{[TOTAL 20 MARKS]}'' if the |hidetitle| option is specifed, see below). % % \item Instructions for answering questions in this section, such as ``\textbf{ANSWER ANY \underline{TWO} QUESTIONS.}''. The argument will be typeset in \textbf{bold face}. If you leave this argument empty it defaults to ``\textbf{ANSWER \underline{ALL} QUESTIONS (TOTAL xx MARKS).}'' (the marks total is omitted if it is zero or if the |hidetotal| option is specified, see below). % % \item A description of the topic of the section (this could also be used to provide further, more detailed instructions). This can be left empty. % \end{enumerate} % % The optional argument to \textsf{examsection} is a list of option keywords that control its behaviour. The available keys are: % \begin{description} % \item[\texttt{showtitle}] Print the title of the section (enabled by default). Use |hidetitle| to suppress this. % % \item[\texttt{showtotal}] Print a summary at the end of the section of the number of marks in the section (enabled by default). Use |hidetotal| to suppress this. This key does not cascade to any questions within the section. % % \item[\texttt{checksubtotals}] Calculate the running total of marks for questions within the section, and verify that this matches the expected number of marks. Use |ignoresubtotals| to suppress this (this also implies |hidetotal|). % \end{description} % % Every section begins on a new page, and the section title is formatted as ``\textbf{\underline{Section A}}'', in \cs{large} size, unless the |hidetitle| option is specified. For example: \\ % % \noindent|\begin{examsection}{25}{}{These questions are remarkably boring.}| \\ % \hspace*{1cm}\vdots \\ % |\end{examsection}| \\ % % \noindent will produce the following (assuming that the actual number of % marks in the question is correct): % % \begin{center} % \fbox{% % \begin{minipage}{0.9\columnwidth} % {\large\noindent\textbf{\underline{Section~A}}} \\[0.5\baselineskip] % \textbf{ANSWER \underline{ALL} QUESTIONS (TOTAL 25 MARKS).} \\ % These questions are remarkably boring. \\ % \hspace*{2cm}\vdots \\ % \mbox{}\hfill\textbf{[SECTION A TOTAL 25 MARKS]} % \end{minipage} % } % \end{center} % % \noindent whereas if we specify |hidetitle|: % % \begin{center} % \fbox{% % \begin{minipage}{0.9\columnwidth} % \textbf{ANSWER \underline{ALL} QUESTIONS (TOTAL 25 MARKS).} \\ % These questions are remarkably boring. \\ % \hspace*{2cm}\vdots \\ % \mbox{}\hfill\textbf{[TOTAL 25 MARKS]} % \end{minipage} % } % \end{center} % % % \subsection{Questions} % \label{Sec:Questions} % % \textsf{ouexam} provides three environments for building examination % questions: \DescribeEnv{question} \textsf{question}, % \DescribeEnv{subquestion} \textsf{subquestion} and \textsf{subsubquestion}, % which correspond to top-level questions, parts of questions, and % \DescribeEnv{subsubquestion} sub-parts of questions respectively. They % produce questions that are numbered according to University examination % formatting requirements. Note that questions are normally numbered % sequentially throughout the entire paper regardless of any section % boundaries. % % All three environments have a single mandatory argument which is the % expected number of marks for the question, part or sub-part. If this % argument is left empty it will default to zero (this has the side effect of % not printing the marks total at the end of the question). This argument works % in much the same way as the first argument to the \textsf{examsection} % environment (see \hyperref[Sec:Sections]{section~\ref*{Sec:Sections}}): % \textsf{ouexam} keeps a running total of the number of marks encountered % within each question part and sub-part, and compares this total with the % expected value when the environment closes. Where appropriate, the running % total is typeset right-justified in the form ``(5 marks)''. For example: % \begin{verbatim} % \begin{question}{5} % \begin{subquestion}{2} % Why is the sky blue? % \end{subquestion} % \begin{subquestion}{3} % Explain in detail how the sky can be made pink. % \end{subquestion} % \end{question} % \begin{question}{1} % Define the term ``floccinaucinihilipilification''. % \end{question} % \end{verbatim} % % \noindent will produce the following: % \begin{center} % \fbox{% % \begin{minipage}{0.9\columnwidth} % \begin{enumerate} % \item % \begin{enumerate} % \item Why is the sky blue? \hfill (2 marks) % % \item Explain in detail how the sky can be made pink. \hfill (3 % marks) % \end{enumerate} % % \item Define the term ``floccinaucinihilipilification''. \hfill (1 % mark) % \end{enumerate} % \end{minipage} % } % \end{center} % % The \textsf{question} environments handle formatting of marks totals % automatically, including considerations such as: % \begin{itemize} % \item whether or not to print the number of marks for a question at all % (they should not be printed if the question has sub-parts, and will also % not be printed if the number of marks is zero); % % \item whether to print ``mark'' or ``marks'' (e.g., question 2 above); and % % \item where to position the number of marks relative to the question, % depending on how full the last line of the question is. % \end{itemize} % % \changes{2.4}{2013/05/31}{NJS Enforced proper question environment nesting.} % The various \textsf{question} environments must be correctly nested in order for the features described above to work correctly, i.e., \textsf{question} at the top level, followed by \textsf{subquestion} and \textsf{subsubquestion}. Any variation to this nesting order will cause an error. % % \changes{2.4}{2013/06/13}{NJS Added \cs{questionskip} to control spacing between questions.} % You can control the spacing between top-level questions by redefining the \DescribeMacro{\questionskip} \cs{questionskip} length. It defaults to \cs{baselineskip}. Note that this applies only to the \textsf{question} environment; there are no equivalent lengths for \textsf{subquestion} or \textsf{subsubquestion}. % % % \changes{2.2}{2010/04/26}{NJS Added time allocation macros.} % \subsection{Time allocations} % \label{Sec-Questions-Time} % % If you wish to suggest a time allocation for completing a question, use the \DescribeMacro{\timeallocation} \cs{timeallocation} macro. The only argument is the number of minutes to be allocated for this question. The macro will output the time allocation in the form: \textbf{[The suggested time allocation for this question is \emph{t} minutes.]} % % If you wish to allow a certain amount of time for candidates to read some text, use the \DescribeMacro{\readingtime} \cs{readingtime} macro. The only argument is the number of minutes to be allocated for reading time. The macro will output the reading time in the form: \textbf{[Allow \emph{t} minutes reading time.]} % % Both macros assume the base unit to be minutes; if you wish to change this you will need to redefine the macros. Otherwise, the argument can be almost anything: text, numbers, etc. % % \textsf{ouexam} currently does not check that time allocations sum correctly. This may be implemented in a future version. % % % \subsection{Marking schedule information} % \label{Sec:Questions:Marking} % % Rather than writing a separate marking schedule for an examination paper, % you can use the \DescribeEnv{marking} \textsf{marking} environment to embed % marking information within questions. By default this information is not % printed (for obvious reasons!), but when it comes time to print a marking % schedule for the examination, use the \textsf{markingschedule} class option % to print the hidden content. The marking information will be set in % \emph{italics} to differentiate it from the main body of the examination, % and \fbox{MARKING SCHEDULE} will also be printed in the header of every % page. % % \changes{2.1}{2004/04/10}{NJS Added driver file tip.} % A useful tip for writing examination papers is to create two separate % ``driver'' documents that are set up the document class for the % ``plain'' and ``marking schedule'' versions of the examination, % respectively. Each should then include a separate document that contains % the actual content of the examination paper, for example: % % \begin{verbatim} % \documentclass[markingschedule]{ouexam} % % \input{exampaper} % contains the actual examination content % \end{verbatim} % % Doing this enables you to build the ``plain'' and ``marking schedule'' % versions independently, without overwriting each other or having to % change the original source file. Simply run \LaTeX\ on the appropriate % driver file to produce the version that you want. See the example files % that came with the \textsf{ouexam} distribution for an example of this % approach in action. % % % \subsection{Miscellaneous} % % Most examinations are marked out of 100, and \textsf{ouexam} defaults to % this. However, if you want an examination that is marked out of some other % number, for example, 90 marks, you can specify this using the % \DescribeMacro{\examoutof} \cs{examoutof} macro. Thus, |\examoutof{90}| % will set the expected number of marks for the examination to 90. This value % is used by \textsf{ouexam} to verify that the marks for all the questions % add up to the expected number of marks for the examination. % % % \section{Errors and warnings} % % In this section are described the error messages and warning produced by % \textsf{ouexam}, and the reasons why they occur. % % % \subsection{Error messages} % % \noindent\texttt{OBSOLETE (\ldots): this document was written for an % earlier} \\ % \texttt{version of ouexam \ldots} \\ % You are trying to use v2.0 or later of \textsf{ouexam} with a document that was written for \textsf{ouexam} v1.2 or earlier.

Group~1 % queries only inactive customers, group~2 queries only bronze status % customers and groups~3 and~4 both query only silver and gold status % customers. Members of any group may query the table at any time and % queries often overlap. % % \item UPDATE, INSERT and DELETE operations on the table are uncommon. % % \item Very few queries are for individual customers; rather, most % queries are based on various combinations of values from % \textsf{status}, \textsf{city}, \textsf{state} and \textsf{country}. % \end{itemize}\medskip % % \begin{subquestion}{3} % Describe and justify an \emph{index-based} physical tuning solution % that will improve the performance of queries on the \textsf{Customer} % table. (No code is required.) % \begin{marking} % Since queries tend to be on combinations of several low-cardinality % columns [1] and the table is very large [1], the most effective % solution would be to place bitmap indexes on status, city, state and % country [1]. % % B-tree indexes on any of the individual columns would not be ideal % because of their low cardinality. A possible alternative is a % composite B-tree index on all four columns [1 for suggesting this if % appropriate], but this is not ideal and would be much larger than % the four bitmap indexes [1 for this explanation if appropriate]. % Hashing is definitely \emph{not} an option, because very few queries % are exact match. % \end{marking} % \end{subquestion} % % \begin{subquestion}{7} % \begin{subsubquestion}{5}\label{nonindex} % Assuming that there are two identical fast disks available, describe % and justify two alternative \emph{non index-based} physical tuning % solutions that will improve the performance of queries on the % \textsf{Customer} table. For each solution include details of how % the two disks will be used. (No code is required.) % \begin{marking} % Alternative 1: partition the table across the two disks based on % status (four partitions, one for each status value) [1]. This will % allow simultaneous parallel access to different parts of the table % by the different groups [1].
