Catalog Number





This session briefly examined the early database management systems (DBMS) software which preceded the development of relational database management systems (RDBMS) which are the focus of this meeting. The early effort by Charles Bachman in the development of the Integrated Data Store (IDS) is mentioned as well as other early dbms products, including IBM's IMS, Cullinane's IDMS, Cincom's TOTAL, MRI's System 2000, CA's Datacom/DB and Software AG's ADABAS. After a discussion of the pioneering efforts of E.F. Codd at IBM Research, significant relational packages are examined by individuals involved in their development and marketing, including: Ingres, Oracle, Sybase, Informix and IBM products such as System R, SQL/DS and DB2. Further discussion will be found in subsequent sessions.
