Abstract

The need for data model independent languages for database systems has become apparent in recent years. They can be used for the conceptual level of a database system, for communication in a distributed database system, for data restructuring, and so on. This paper proposes a language,wcrl, to fill this need and compares it with the very few other languages which have been developed almost concurrently to fill the same need.

Key words

Data retrieval database language data model independent language
