To support a number of emerging applications we propose a persistent complex object database language which is “‘value” based. The object space is built through the set and tuple object constructors, with practically no normalization constraints on the nesting levels. The proposed persistent database language can serve both as an interface language to the database management system in itself or as the target language of a conceptual data language. Some of the features of the language include: (i) Notion of “path”s capturing logical references to retrieve and update the persistent database, (ii) a rich set of allowable schema types, including disjuncts, and (iii) a collection of powerful operator constructors for sets.
