title: How to connect to a different database in OpenERP?
body: <p>How would one go about connecting to a different database based on which module is being used? Our scenario is as follows:</p>
  
  <p>We have a standalone application with its own database on a certain server and OpenERP running on different server. We want to create a module in OpenERP which can utilise entities on the standalone application server rather than creating its own entities in its own database, is this possible? How can we change the connection parameters that the ORM uses to connect to its own database to point to a different database?</p>
  
  <p>Ofcourse, one way is to use the base_synchro module to synchronise the required entities between both database but considering the large amount of data, we don't want duplication. Another way is to use xmlrpc to get data into OpenERP but that still requires entities to be present in OpenERP database.</p>
  
  <p>How can we solve this problem without data duplication? How can a module in OpenERP be created based on a different database?</p>
