Abstract
SQL (Structured Query Language) was first developed by IBM and produced for SQL/DS and DB2 database management systems. It has since been adopted for numerous database packages, including dBase IV, Informix, Oracle and Ingres as a command language for creating and modifying databases, manipulating data within them and controlling user access. Although there is much similarity between the different implementations, there are a few differences. SQL has been adopted as an ISO standard, but unfortunately the standard has certain defects which have led most implementations to include extensions.
