code base for
Microsoft SQL Server (prior to version 7.0) originated in
Sybase SQL Server, and was
Microsoft's entry to the enterprise-level database market, competing against
IBM, and, later,
Sybase itself. Microsoft, Sybase and
Ashton-Tate originally teamed up to create and market the first version named SQL Server 4.2 for
OS/2 (about 1989) which was essentially the same as Sybase SQL Server 4.0 on
VMS, etc. Microsoft SQL Server for NT v4.2 was shipped around 1992 (available bundled with Microsoft
OS/2 version 1.3) and was a simple port from OS/2 to NT. Microsoft SQL Server v6.0 was the first version of SQL Server that was architected for NT and did not include any direction
