The meaning of this parameter differs according to the database engine you use. For example, this value returns only MySQL information when
            returning values from CreateDBInstanceReadReplica since read replicas are only supported for MySQL. MySQL Contains the name of the
            initial database of this instance that was provided at create time, if one was specified when the DB instance was created. This same name is
            returned for the life of the DB instance. Type: String Oracle Contains the Oracle System ID (SID) of the created DB instance. Not
            shown when the returned parameters do not apply to an Oracle DB instance.
