When the HiRDB External Data Access facility is used, the HiRDB interface can be used to access the tables of multiple databases constructed from other database management systems, including products of other companies. Also, when multiple databases of other types exist, their information can be viewed and updated as one table using foreign table or view table. To use the HiRDB External Data Access facility, HiRDB External Data Access is required.
