In the previous exercise you installed a business data connectivity model into SharePoint Online and the external content type you created became available tenancy wide and could be used in any site collection — restricted by permissions, of course. However, the SharePoint 2013 app model provides a new opportunity for you to deliver Apps for SharePoint that have the BDCM deployed at the app-level so it is scoped only to that specific app for SharePoint. This opens up a whole new opportunity to deliver Apps for SharePoint from the Office.com Store that have a self-contained BCS connection to any OData source that you choose to provide. The key point is that app-level solutions must connect to OData sources; that’s the only connection type supported in an app for SharePoint. In the following activity you build an app for SharePoint with an OData connection and see how it’s defined to SharePoint.
