Structured Query Language, aka Structured Query Language, is an actively used query language created in 1974. SQL ( ( listen) ESS-kew-EL or ( listen) SEE-kwəl or SKWEEL, Structured Query Language) is a domain-specific language used in programming and designed for managing data held in a relational database management system (RDBMS), or for stream processing in a relational data stream management system (RDSMS). In comparison to older read/write APIs like ISAM or VSAM, SQL offers two main advantages: first, it introduced the concept of accessing many records with one single command; and second, it eliminates the need to specify how to reach a record, e.g. with or without an index.
