SQL Server Fundamentals


SQL stands for standardized query language or specialized query language. It is a database management system which has been developed by Microsoft. It stores and recovers the data on the request of other applications. It also updates the data in the database. SQL was initially released by Microsoft and Sybase. After a few years, their association was concluded and the server was released again by Microsoft without any other companionship. The versions of SQL released by Microsoft are consist of some advanced storage and security options such as XML data type support, DVMS and database mirroring. The first version of SQL was released in 1989. It has been made available in several languages including French and Chinese.

In SQL data is stored in Tables containing rows and columns. Tables that are of similar security requirements can be stored in the same database.
