Microsoft SQL Server
A relational database management system (RDBMS) which is part of Microsoft's BackOffice family of servers. SQL Server was designed for client/server use and is accessed by applications using SQL. It runs on Windows NT version 3.5 or higher and is compliant with the ANSI SQL-92 and FIPS 127-2 SQL standards.
SQL Server supports symmetric multiprocessing hardware; SNMP, ODBC, and major open standard communications protocols. It has Internet integration, data replication, and data warehousing features.
Microsoft SQL Server was originally developed by Sybase Corporation but the cooperation was broken sometime [when?] before version 6.0.
