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. Hence, the database system is restricted to a single data model and a
specific data language. One 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
limitations.
This thesis presents a methodology for supporting the Functional Data Model and
the Data Language DAPLEX for the MLDS. Specifically, we design an interface which
translates DAPLEX data language calls into attribute-based data language (ABDL)
requests. A description of the software engineering aspects of the implementation and an
overview of the modules which comprise our DAPLEX language interface are provided.
