25 years of DB2

June 7th marked the 25th anniversary of the launch of IBM’s DB2 database on the MVS operating system.

This InformationWeek article describes how a close knit community of researchers and programmers┬ácaused the “accidental birth of an empire”.

At first, relational database was a highly mocked product, halting in its performance compared to the programmed-path systems. Skeptics like John Cullinane, founder of Cullinet Software, once took this reporter aside to instruct him that relational database would never amount to anything compared to his firm’s IDMS product. Last year, relational database represented an $18.6 billion a year market, according to IDC. Ecommerce would be impossible without it.

ITWorldCanada discusses the contributions of the IBM Toronto Lab and the development of DB2 for Linux, UNIX, and Windows.
