Structured Query Language (SQL) is one of the reasons we have the World Wide Web as it is responsible for querying and editing information that is stored on databases around the world that manage the system. SQL has been around since the 70’s but now is far more flexible to users  with its capability of supporting distributed databases, which means computers are networked and connected at all times. This greatly improves processes strength and allows for new functionality such as support for XML, triggers, regular expression matching, recursive queries and standardized sequences.

SQL is based on many different elements that can handle all necessary language commands; Clauses, expressions, predicates, queries and statements make up these elements. This enables SQL to retrieve data, update/insert/delete records from databases, create new databases and can set permissions in those databases. These commands can be summed up as: Select, Insert, Delete, Create and Drop. These commands can essentially enable the user to do anything to databases.

In the end, SQL is a very useful and helpful program to sort, find, view and edit information stored in databases all around the world.
