The three-schema approach, or the Three Schema Concept, in software engineering is an approach to building information systems and systems information management from the 1970s. It proposes use three different views in systems developement, in which conceptual modelling is considered to be the key to achieving data integration. The notion of a three-schema model consisting of a conceptual model, an external model, and an internal or physical model was first introduced by the ANSI/X3/SPARC Standards Planning and Requirements Committee directed by Charles Bachman in 1977. The ANSI/X3/SPARC Report characterized DBMSs as having a two schema organization.
