When was SQL created?
SQL
SQL was initially developed at IBM by Donald D. Chamberlin and Raymond F. Boyce after learning about the relational model from Ted Codd in the early 1970s. This version, initially called "SEQUEL" ("Structured English Query Language"), was designed to manipulate and retrieve data stored in IBM's original quasi-relational database management system, System R, which a group at IBM San Jose Research Laboratory had developed during the 1970s.
OpenBase
OpenBase SQL is a relational database server software, originally developed for the OpenStep platform. First released in 1991, OpenBase is available today for several platforms, although the bulk of its users are on Mac OS X. The system supports common access methods via JDBC and C, however it is optimized for use in conjunction with a variety of Macintosh-based development tools like WebObjects, RealBasic and Omnis Studio.
