title: How to use a PostgreSQL DB as XMLA datasource?
body: <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>
