Or you could just follow these lil instructions here ;) To change the Connection at runtime you have to basically set the object store coordinator You create a custom object store coordinator like this: <pre class="lang-java prettyprint-override"><code>NSMutableDictionary<String, String> temp = new NSMutableDictionary<String, String>(); temp.put("URL", String.format("%s?useBundledJdbcInfo=true", url)); temp.put("username", username); temp.put("password", password); temp.put("name", name); connectionDictionary=temp.immutableClone(); // Create a new Object store coordinator objectStoreCoordinator = new ERXObjectStoreCoordinator(); ERXModelGroup.setModelGroupForObjectStoreCoordinator( objectStoreCoordinator, ERXModelGroup.defaultGroup() ); // Set the model that you want to use to connect to multiple databases EOAdaptor adaptor =ERXDatabaseContext.registeredDatabaseContextForModel( ERXModelGroup.defaultGroup().modelNamed("YourModelName"), objectStoreCoordinator ).adaptorContext().adaptor(); // update the connection dictionary adaptor.setConnectionDictionary( updateDictionary(adaptor.connectionDictionary(), connectionDictionary) ); </code></pre> With this you can easily create a new editing context that points to the database of your choice <pre class="lang-java prettyprint-override"><code>ERXEC.newEditingContext(objectStoreCoordinator); </code></pre> If your application is used by multiple users and they all need to switch between multiple DBs without interfeering with each other, I recommend that you not use Shared Editing Context. Like this you avoid people changing the object store coordinator to cause the others to point to that database too (not so funny).

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
