<h2><a name="3_Introduction">3. Introduction</a></h2>
<p>This is a list of features we propose to deliver in future releases of
Mondrian. Each feature is linked to a high-level description. Complex features
will have more detailed specifications in a separate document.</p>
<p>Component designs
are added to the <a href="overview.html">architectural overview</a> as
necessary. Short term, you can put designs into an appendix.</p>
<p>It occurs to me that we haven't really defined who our customer is. Our main
customer, I would contend, is someone using a web application (such as the
sourceforge usage chart, <a href="http://sourceforge.net/project/stats/?group_id=35302">http://sourceforge.net/project/stats/?group_id=35302</a>).
In some cases we will deliver apis and servlets to a second kind of customer, a
developer. But almost every feature should have a deliverable -- perhaps just a
sample application -- which can be used by the web-user.</p>

<h2><a name="5__Specifications">5. Specifications</a></h2>
<h3><a name="5_1_Server">5.1. Server</a></h3>
<p>See <a href="overview.html">architectural overview</a>.</p>
<h3><a name="5_2__Html_pivot_table">5.2. Html pivot table</a></h3>
<p><i>Sean, please complete this.</i></p>
<p><i>Does the pivot table support cell-selection in this release?</i></p>
<h4><a name="5_2_1_Basic_drill_through">5.2.1. Basic drill through</a></h4>
<p>Use case: User runs a query in the pivot table. Presses 'show data' button.
An HTML table is displayed, containing the rows of the fact</p>
<p>If the pivot table supports selection of cells, rows or columns, the rows
shown should relate only to selected cells.</p>
<p><i>Julian: It's not hard to implement the server-side part of it (given a set of
coordinates, e.g {([Time].[1997], [Store].[USA]), ([Time].[1998],
[Store].[USA].[CA])}, return a select statement/parse tree of a select
statement/jdbc result set for the fact table rows which went into those cells).
The hard part is to incorporate it into the ui in a non-trivial way. (Which end
user wants to see a table with columns headed REGION_ID, TIME_ID, UNIT_SALES,
and a bunch of surrogate keys?)</i></p>
<h4><a name="5_2_2_Chart_button">5.2.2. Chart button</a></h4>
<p>Use case: User runs a query in the pivot table. Presses 'pie chart' button.
Data is rendered in pie chart.</p>
<h4><a name="5_2_3__Actions">5.2.3. Actions</a></h4>
<p><i>Tony, please specify.</i></p>
<p><i>Julian: These come under the aegis of the pivot table until we have an
independent controller. It should be easy to shoehorn their
metadata into the catalog (of which FoodMart.xml is an example, and Mondrian.xml
is the specification).</i></p>
<h4><a name="5_2_4__Drill_anywhere">5.2.4. Drill anywhere</a></h4>
<p>Use case: User runs a query in the pivot table. They choose a column (for
example, day of week) which is not a dimension, and drill on it. (Behind the
scenes, the server is creating a dimension on the fly.)</p>
<h3><a name="5_3_Html_servlet">5.3. Html servlet</a></h3>
<p>Runs an mdx statement, renders the results as an html table.</p>
<p><i>Sean, please complete this. Sketch out the major components (reference
javadoc if these are classes), and describe the sample code we will deliver,
list preferences.</i></p>
<h3><a name="5_4_Charts">5.4. Charts</a></h3>
<p><i>Tony, please complete this.</i></p>
<p><i>Possible deliverables:</i></p>
<ul>
<li><i>api & example code render mdx results as chart</i></li>
<li><i>servlet</i></li>
<li><i>chart wizard</i></li>
</ul>
<p><i>What formats shall we support in 1.0? We must do either JPEG or GIF.</i></p>
<h3><a name="5_5_Web_test_harness">5.5. Web test harness</a></h3>
<p><i>Sean, please complete this.</i></p>
