SQL stands for Structured Query Language. SQL is a standard language that was designed to query and manage data in relational database management systems (RDBMS). Various RDBMS implementations exist, but the term SQL Server is typically used to refer to Microsoft SQL Server. This is Microsoft’s industrial RDBMS that provides a full data management engine and manipulation solution. SQL Server uses Transact-SQL (T-SQL) as its programming language. This is an extended version of the ANSI and ISO standard SQL language. T-SQL has extensions to allow procedural programming, string and math processing, and other additions that make it a Turing complete programming language.
