About installing a database linked to a SQL Server instance
You can locally install an SQL Server 2012 Express evaluation database. Besides, you can locally or remotely install an evaluation database or production database that is linked to an instance of SQL Server. All installations allocate 100 MB of storage for the database. SQL Server automatically allocates more space when it is needed. To install a database linked to an instance of SQL Server, Symantec recommends that you first install a new instance of SQL Server that conforms to the installation requirements
You can install a database to an older, existing instance, but the instance must be configured properly or your database installation fails. For example, if the authentication configuration is not set to Mixed Mode, your installation fails.
