How to use a PostgreSQL DB as XMLA datasource?
<p><strong>Basis:</strong></p>

<ul>
<li>PostgreSQL database with normal and reporting data</li>
<li>Downloaded the Mondrian zip from <a href="https://github.com/pentaho/mondrian/releases/tag/4.5.0.3-R" rel="nofollow">here</a></li>
<li>I have a client pivot grid component (<a href="http://js.devexpress.com/Demos/WidgetsGallery/#demo/data_grid-pivot_grid-olap_data_source" rel="nofollow">DevExtreme Web</a>)</li>
</ul>

<p>As i understand it so far, i have to use a OLAP-server that functions as connector between MDX querys and a SQL database to provide XMLA as datasource. Therefor i want to use the Mondrian OLAP-server.</p>

<p><strong>Question:</strong></p>

<p>Now i need to start the Mondrian OLAP-server, connect it to the PostgreSQL database and provide a OLAP-schema.</p>

<ol>
<li>How to start the Mondrian OLAP-server?</li>
<li>How to connect it to a PostgreSQL database?</li>
<li>How to provide a schema to the mondrian server?</li>
<li>And finaly, how to connect to the mondrian server?</li>
</ol>

<p>I can't find any step by step guide or any usefull documentation of mondrian. It's all a big cloud to me.</p>
