Database Types 

The SAP J2EE Engine supports several databases provided by different database vendors.

The O/R mapping for container-managed entity beans depends on the type of the underlying database.

To ensure that your database mapping is correct and compatible with the database you are using, use the NetWeaver Developer Studio to specify the O/R mapping.

For more information about mapping between the Java types and the corresponding JDBC types in the different databases, see the documentation of the database you are using.
