2.4 Mapping of CMP fields and data types

This section describes the mapping of the CMP fields and data types.

In a CMP field, the specifiable range and the availability to specify in the primary key is fixed for each Java data type. Furthermore, the support for the Java data type and the SQL data type of the database will differ for each type of the database.

The following table describes the organization of this section:
