The sidebar shows the list of Databases as a tree of folders (like the Virtual DataPort Admin Tool does). You can click on any database name, so the list of results on the right side would only contain elements (views and web services) of the selected database.
If the selected database has some custom properties groups assigned, they also will be shown in this page.
The list of elements in the tree can be filtered by using the Search option at the top of this sidebar.
The button to edit the database is only visible if the user has administration privileges.
The Show Connection button shows the different URIs that would be needed to connect to the current Virtual DataPort database through JDBC, ODBC, REST and OData. In the case of REST it shows the URI to query a web service deployed on that database.
