Traditionally, the design and implementation of a conventional database system begins with the selection of a data model, followed by the specification of a model-based data language. An alternative to this traditional approach to database system developement is the multi-lingual database system. 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. This thesis presents the specification and implementation of a hierarchical/DL/I language interface for the MLDS. Specificallly, it presents the specification and implementation of an interface which translate DL/I data language calls into attribute-based data language requests. The author describes the software engineerig aspects of the implementation and an overview of the four modules which comprise the DL/I language interface.
