Informix
A Unix database vendor based in Menlo Park, California, USA. The company was one of the first ISV to deliver a product on the OS/2 market, and the first to deliver a database product in the form of the SQL Informix Database and related toolsets in January 1988, beating out main competitor and arch enemy Oracle by a few months. However after IBM and Microsoft started delivering their own multi user database products to the OS/2 market a year later the company changed its stance on the platform completely and used every opportunity to mention its unimportance, despite that Informix continued to update their OS/2 offerings into the latter half of the 90's.
