Description
The architecture of most commercial DBMSs is based on the ANSI-SPARC architecture (1975). Itwasdevised by American National Standards Institute (ANSI) and Standards Planning AndRequirementsCommittee (SPARC). The ANSI-SPARC model of a database identifies three distinct levels atwhichdata items can be described. These levels form a three-level architecture comprising of an external level,aconceptual level, and an internallevel
