DBA-Layer
The DBA layer was used in earlier versions of FirstSpirit under the name "SingleProjectLayer". It was introduced for being able to create FirstSpirit schemata in a project even without intervention by a database administrator.
In contrast to the standard layer, no explicit DB schema for saving tables is specified in the layer definition for a DBA layer. FirstSpirit independently creates the DB schemata belonging to the FirstSpirit schemata in the DBMS. The name of the DB schemata is composed of the schema and project ID in the process.
The user specified in the layer has to have the permissions to create DB schemata in the DBMS to use a DBA layer. In many DBMSs, this is only possible with permissions similar to a database administrator'.
