The implementation of a functional/daplex interface for the multi-lingual database system.

Abstract

Traditionally, the design and implementation of a conventional database system begins with the choice of a data model followed by the specification of a model-based data language. Thus, the database system is restricted to a single data model and a specific data language. An alternative to this traditional approach to database-system development is the multi-lingual database system (MLDS). This alternative approach enables the user to access and manage a large collection of databases via several data models and their corresponding data languages without the aforementioned restriction. In this thesis we present the implementation of a functional/Daplex language interface for MLDS. Specifically, we present the implementation of an interface which translates Daplex language calls into attribute-based data language (ABDL) requests which, as the kernel language, support all other data language interfaces.
