Database Name
Specify the application database name used for the site.
If the server name or database name contains a dash, enclose the name in brackets. For example: [SL900-DB]
The application database name specified here is used by system processes such as intranet shared users, and by transactional replication to build appropriate links and relationships to other sites in the same database, or in other databases. You can change the name here (for example, if you have backed up and restored the database with a new name), but be aware that you must also manually change the server and database name in the Configuration Manager.
