In 1985, Microsoft and IBM announced "a long-term joint development agreement for development of operating systems and other systems software products.“
This announcement was the beginning of OS/2, a successor to the Microsoft MS-DOS operating system. OS/2 would be a more complete and robust operating system.
OS/2 was formally announced in April 1987, with shipment promised by the end of the year.
But shortly after the joint declaration, IBM announced a special higher-end version of OS/2 called OS/2 Extended Edition. This more powerful version would include the base OS/2 operating system plus an SQL RDBMS called OS/2 Database Manager (now famous as DB/2)
But if IBM could offer a more complete OS/2 solution, who would buy Microsoft OS/2? Clearly, Microsoft needed to come up with an answer to this question.

Microsoft needed a database management system (DBMS) product, hence Microsoft turned to Sybase, Inc., an upstart in the DBMS market. The deal between the two companies was a win-win situation.
In 1988, a new product was announced with the somewhat clumsy name Ashton-Tate/Microsoft SQL Server. This new product would be a port of Sybase DataServer to OS/2, marketed by both Ashton-Tate and Microsoft.
Ashton-Tate, Microsoft, and Sybase worked together to debut SQL Server on OS/2. (This was the first use of the name SQL Server). Today, Sybase's database server is known as Sybase Adaptive Server
The following timeline summarizes the development history of SQL Server:
- 1987 Sybase releases SQL Server for UNIX.
- 1988 Microsoft, Sybase, and Aston-Tate port SQL Server to OS/2.
- 1989 Microsoft, Sybase, and Aston-Tate release SQL Server 1.0 for OS/2.
- 1990 SQL Server 1.1 is released with support for Windows 3.0 clients.
