Data connections are physical connections to a database. In Server Explorer, the Data Connections node has a list of every established database connection. To start the database creation process, right-click the Data Connections node and select the Create New SQL Server Database option. In the resulting dialog box (see Figure 13.2), you need to provide a server name, login credentials, and a name for the new database.
This immediately creates the indicated database and adds a connection to the new database under the Data Connections node. Figure 13.3 shows the newly created Contoso database added to the list of connections.
You can also establish a connection to an existing database. Again, you right-click the Data Connections node; this time, though, you select the Add Connection option. The Add Connection dialog box (see Figure 13.4) is similar to the New Database dialog box. You specify a data source, server name, login credentials, and database name/database filename to connect to the database.
Under each connection are folders for the following classes of database objects:
Database diagrams (not available with SQL Server 2012)
Tables
Views
Stored procedures
Functions
Types
Assemblies
These folders are the launching point for creating corresponding objects within the database.
