There are also specialised versions, such as the Azure SQL Database which is the cloud-based version of Microsoft SQL Server. SQL Server has many different features, such as XML data type support, dynamic management views (DMVs), database mirroring and full-text search.
Microsoft’s first foray into SQL servers was in 1988, when the company joined forces with Ashton-Tate and Sybase to create a variant of Sybase SQL Server for IBM OS/2. The Sybase SQL Server is now known as SAP ASE (Adaptive Server Enterprise), following the company becoming part of SAP AG. ASE runs predominately on Unix, although it is also available on Microsoft Windows.
The main competitors to The SQL Server are Oracle Database (DB) and MySQL. The latter is an open source relational database management system which is popular for use in web applications, while Oracle’s relational database was the world’s first to support SQL.
