SQL

SQL, short for Structured Query Language, is a standard language used when interacting with web databases. A standard SQL query can perform tasks such as updating, deleting and searching data within a database. SQL queries limit the amount of results returned from the database to the web browser. For instance, an online banking page would use a SQL query that would limit the returned results to records associated with a specific user's account information. The SQL query to perform that task may look something like "SELECT * FROM bankers WHERE name = 'John Smith'". Popular databases that operate on the SQL platform are Microsoft SQL Server, MySQL, PostgreSQL and Oracle.
