SQL/DS [1] (Structured Query Language/Data System), [2] released in 1981, was IBM's first commercial relational-database management system. [3] It implemented the SQL database-query language.
SQL/DS ran on the DOS/VSE and VM/CMS operating systems. [4] A little later, IBM also introduced Db2, another SQL-based DBMS, this one for the MVS operating system. The two products have coexisted since then; however, SQL/DS was rebranded as "DB2 for VM and VSE" in the late 1990s. [5]
Software AG's Natural 4GL was an early third-party software product that facilitated using SQL/DS. Software AG used the name Natural 2/SQL-DS and, later on, for a related offering, Natural 2/DB2. [6] [7]
The product was called SQL/DS (Structured Query Language/Data Store) and ran under the DOS/VSE operating system environment
