Sql allows users to access data in relational database management systems, such as oracle, sybase, informix, microsoft sql server, access, and others, by allowing users to describe the data the user wishes to see. sql also allows users to define the data in a database, and manipulate that data. While it is impossible to predict what model will emerge as a winner in the future, it seems reasonable to assume that relational databases are here in for a long haul and have not yet reached their potential; sql as the language of the rdbms will keep its importance in the database world. The structured query language (sql) is a language which describes how to create, update and query relational databases. a relational database is conceptually quite simple.
