ABSTRACT

DAPLEX is a database language which incorporates: a formulation of data in terms of entities; a functional representation for both actual and virtual data relationships; a rich collection of language constructs for expressing entity selection criteria; a notion of subtype/supertype relationships among entity types. This paper presents and motivates the DAPLEX language and the underlying data model on which it is based.
