Description: An RDBMS designed to be strictly relational, unlike SQL. An important example of the model independence of a particular implementation such as SQL.
IBM United Kingdom Limited (retired 2004) The planning of BS12 started in 1978, with a decision that the new state-of-the-art DBMS for IBM's Bureau Service would be a relational one, but the design and implementation took another four years. It became available to customers in 1982, at least two years after Oracle and SQL/DS. Although the Bureau Service died in about 1985, I am pretty sure one internationally available BS12 service is still running in The Netherlands. (IBM's US subsidiary, Service Bureau Corporation developed some pre-relational dbms software in the early sixties. When SBC was sold to CDC under consent decree litigation, the business carried on in EMEA and AFE, and we inherited that software. I worked for the small lab that made that dbms software into a deliverable. Business System 12 was its supersedent.)
