The Implementation of a Network CODASYL-DML Interface for the Multi-Lingual Database System.
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 development is the multi-lingual database system (MLD...

Summary: | 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 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. This thesis presents the specification and implementation of an interface which translates CODASYL-DML data language calls into attribute-based data language (ABDL) requests. It describes the software engineering aspects of the implementation and an overview of the four modules which comprise our CODASYL-DML language interface. (Author) |
