Abstract : Traditionally, the design and implementation of a conventional database system begins with the choice of a data model followed by the specifications 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 affords the user the ability 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 a methodology for supporting network (CODASYL) database management on the MLDS. Specifically, we design an interface which translates CODASYL-DML statements into ABDL requests. We describe the data structures, the control mechanisms, and the functions/procedures necessary to implement such a system. Keywords: Multi-lingual Database System (MLDS), Multibackend Database System (MBDS), Attribute-based Data Model, Attribute-based Data Language (ABDL), CODASYL Data Model; Network Database Translation.
