db_QUERY

Two companion products for db_VISTA were introduced in 1986. Raima’s db_QUERY introduced the first SQL-like query and report writing utility for a network model database system. Today, db_QUERY no longer exists. However, Raima does offer SQL in all its DBMS products.

Raima’s db_REVISE is still included with the RDM product and is used to modify a database definition and make whatever revisions to the existing data that are necessary to accommodate the changes.
