in full structured query languagecomputer language (computer programming language) designed for eliciting information from databases (database).In the 1970s computer scientists began developing a standardized way to manipulate databases, and out of that research came SQL. The late 1970s and early '80s saw the release of a number of SQL-based products. SQL gained popularity when the American National Standards Institute (ANSI) adopted the first SQL standard in 1986. Continued work on relational databases led to improvements in SQL, making it one of the most popular database languages in existence. Some large software companies, such as Microsoft Corporation and Oracle Corporation, produced their own versions of SQL, and an open-source (open source) version, MySQL, became extremely popular.SQL works by providing a way for programmers and other computer users to get desired information from a database using something resembling normal English. On the simplest level, SQL consists of only a few commands: Select, which grabs data; Insert, which adds data to a database; Update, which changes information; and Delete, which deletes information. Other commands exist to create, modify, and administer databases.SQL is used in everything from government databases to e-commerce sites on the Internet. As the popularity of SQL grew, programmers and computer scientists continued to optimize the way that relational databases work.* * *
