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 three 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. % This is the default page style. % % \item[\textsf{lastpage}] \DescribeMacro{lastpage} This is similar to % \textsf{plain} but with ``\textbf{END}'' instead of ``\textbf{TURN % OVER}''. It is used for the last page of the examination. You % normally will not have to use this yourself---the class should take % care of it automatically. The class does however occasionally seem % to get confused, so there may times when you have to set the page % style of the last page manually. It will be fairly obvious when you % need to do this---the usual effect is that the last page % has ``\textbf{TURN OVER}'' printed on it when it should not. % % \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. As with \textsf{lastpage}, 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, \ldots. Rather than redefine the existing section macros, this class % defines an \DescribeEnv{examsection} \textsf{examsection} % environment\footnote{Note that the old \cs{newsection} macro has been % retained for backwards compatibility with earlier development versions of % \textsf{ouexam}. The \textsf{examsection} environment replaces this macro % and should be used in all new documents.} 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. \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. % 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]}'' as an additional verification. % % \item Instructions for answering questions in this section (such as % ``Answer any TWO questions.''). If you leave this argument empty it % defaults to ``ANSWER ALL QUESTIONS.''. % % \item A description of the topic of the section. This can be left % empty. % \end{enumerate} % Every section begins on a new page, and the section title is formatted as % ``\textbf{\underline{Section A}}'', in \cs{large} size. 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] % ANSWER ALL QUESTIONS. \\ % These questions are remarkably boring. \\ % \hspace*{2cm}\vdots \\ % \mbox{}\hfill\textbf{[SECTION A 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 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); % % \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{2.3.1}{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{2.2}{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 examinationss 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{INCOMPATIBLE (\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}. You should be able to download a copy of v1.2 from the % same location that you found the current version. \\ % % \noindent\texttt{no \cs{examyear} was specified} \\ % \noindent\texttt{no \cs{department} was specified} \\ % \noindent\texttt{no \cs{papernumber} was specified} \\ % \noindent\texttt{no \cs{papertitle} was specified} \\ % You have not specified one of these macros.

You should use the \textsf{examsection} environment % instead. \\ % % \changes{2.0.2}{2002/08/22}{NJS Added `FY' to \cs{semester} error % description.} % \noindent\texttt{invalid value `\ldots' for \cs{semester}; valid values are % `1', `2', `SS',} \\* % \texttt{`FY' and `SP'.

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.

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 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 three 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. % This is the default page style. % % \item[\textsf{lastpage}] \DescribeMacro{lastpage} This is similar to % \textsf{plain} but with ``\textbf{END}'' instead of ``\textbf{TURN % OVER}''. It is used for the last page of the examination. You % normally will not have to use this yourself---the class should take % care of it automatically. The class does however occasionally seem % to get confused, so there may times when you have to set the page % style of the last page manually. It will be fairly obvious when you % need to do this---the usual effect is that the last page % has ``\textbf{TURN OVER}'' printed on it when it should not. % % \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. As with \textsf{lastpage}, 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, \ldots. Rather than redefine the existing section macros, this class % defines an \DescribeEnv{examsection} \textsf{examsection} % environment\footnote{Note that the old \cs{newsection} macro has been % retained for backwards compatibility with earlier development versions of % \textsf{ouexam}. The \textsf{examsection} environment replaces this macro % and should be used in all new documents.} 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. \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. % 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]}'' as an additional verification. % % \item Instructions for answering questions in this section (such as % ``Answer any TWO questions.''). If you leave this argument empty it % defaults to ``ANSWER ALL QUESTIONS.''. % % \item A description of the topic of the section. This can be left % empty. % \end{enumerate} % Every section begins on a new page, and the section title is formatted as % ``\textbf{\underline{Section A}}'', in \cs{large} size. 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] % ANSWER ALL QUESTIONS. \\ % These questions are remarkably boring. \\ % \hspace*{2cm}\vdots \\ % \mbox{}\hfill\textbf{[SECTION A 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 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); % % \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{2.2}{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 examinationss 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{INCOMPATIBLE (\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]. 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.
