SQL Server has actually been around for quite a while, in one form or another. SQL Server was originally introduced in 1988. The first version was a joint venture between Sybase and Microsoft, ran only on OS/2, and was a complete flop in themarketplace. In 1993, SQL Server 4.2 for Windows NT Advanced Server 3.1 was
released. This version made some small advances in the marketplace, but still didn't
have what it needed to make it an enterprise-class RDBMS. Microsoft and Sybase went their separate ways in 1994, and shortly afterward Microsoft released SQL Server 6.0. In 1996, SQL Server 6.5 was released. This version of SQL Server succeeded in the marketplace primarily because it had the speed, power, ease-ofuse, and low cost that purchasers and IT staffers were looking for.
In addition to the features that administrators were looking for, part of SQL Server'ssuccess has to do with the direction that the marketplace took around the same time that SQL Server 6.5 was released. For the most part, the market was moving towardfaster and cheaper Intel-based servers running Windows NT Server. This meant that,on abandoning other platforms, when there was a need for an RDBMS, SQL Server
became the natural selection.
SQL Server 7.0, released in early 1999, moved SQL Server into the enterprise database arena. Although previous versions of SQL Server contained large amounts of the original Sybase code, SQL Server 7.0 is said to be 100% Microsoft code.It's even said that Microsoft developers threw a party when the final lines of original code were removed. If SQL Server 7.0 is not a complete rewrite, it is pretty close.The latest version, SQL Server 2000, allows Microsoft to step a little further into the
enterprise database arena. It has a large amount of new features that make it a stronger competitor of the largest, most widely accepted enterprise database—Oracle. SQL Server will probably never completely take over this particular database arena, but it will continue to make strides to do so.
