Mapping out the DBMS territory
Source: Data Management Magazine Date:February, 1983
In the 1970s there were no more than two dozen widely marketed DBMS product lines. Non-IBM DP shops, using equipment such as Univac, Honeywell or Burroughs, simply took the DBMS offered by the hardware vendor. IBM shops could choose IBM’s IMS and DL/1 products, or they had a choice of a handful of successful, competing products such as Software AG’s ADABAS, Cincom Systems’ TOTAL and Cullinane’s (Cullinet) IDMS.
Today, there are 75 to 100 qualified software vendors marketing DBMS packages for all types of computers-from micros to mainframes. Many different logical models are represented in the products being actively marketed: Hierarchical, inverted, CODASYL, master/ detail and relational.
This article provides an overview of where the DBMS market was heading in the early 1980’s.
