Over the years, the IBM Information Management System (IMS/VS) has been developed to meet expanding user needs. During that time, a parallel development has taken place. The relational data model grew from Codd's original theory to a practical data base prototype. Now a new data base management system, IBM Database 2 (DB2), has been built on the relational model. This paper discusses the implementation and design considerations for the integration of IMS and DB2 from the user's viewpoint. It also presents the attachment facilities from a design perspective.
