Specifies the name of the database vendor for which tables can be created. Allowed values are db2, mssql, oracle, pointbase, and sybase, case-insensitive.
If no value is specified, a connection is made to the resource specified by the jndi-name subelement of the cmp-resource element, and the database vendor name is read. If the connection cannot be established, or if the value is not recognized, SQL-92 compliance is presumed.
This element can be overridden during deployment. See Table 7–4.
