Adding manual databases to the catalog

Users can create "manual" (without a connection) databases in the repository. This can be useful for various occasions:

1. You want to import tables from an external source (with Excel or copy & paste).
2. You want to model data.
3. You want to create Subject Areas/Modules unrelated to any specific database (for instance, if you want to collect objects from various databases).
4. You want to document files that need to be added to an existing database.

To add a manual database, click Add Source in the ribbon and choose the Manual database option.
