Data Source Explorer provides a tree view of all registered data sources. It breaks down the components of each data source and categorizes databases and corresponding database objects by object type and underlying SQL code. This feature provides you with a view of the contents of data sources in your enterprise in an easily navigated and cataloged interface.
Data Source Explorer sorts databases and database objects by category within DB Optimizer. If data sources are particularly large or complex, or you are only developing specific objects, you can apply database object filters on the view in Data Source Explorer.
