MS SQL refers to Microsoft's SQLServer database server, which is a database platform and provides a complete solution from server to terminal. The database server is a database management system for establishing, using and maintaining databases. SQL Server was not originally developed by Microsoft itself, but was produced in cooperation with Sybase to compete with IBM. Its earliest developer was Sybase, and Microsoft also cooperated with Sybase to develop the version of SQL Server. Microsoft also transplanted SQL Server 6.0 to Windows NT (version 3. 1 at that time), and independently developed version 6.0 of SQL Server after terminating its cooperation with Sybase, and all the subsequent SQL Servers were developed by Microsoft itself.
