Connecting to databases
When the host is registered, and the database registration is complete, you can establish connection to your database.
The simplest way to connect to a database is to double-click its node in the Database Explorer tree. The same operation can be performed by selecting the Connect to Database item of the database node context menu, or by using the Database | Connect to Database main menu item.
Alternatively, you can use the Shift+Ctrl+C shortcut to connect to your database.
