Abstract:

Typically, the design and implementation of a conventional database system begins with the choice of a data model, the specification of a model-based data language, and the design and implementation of a database system which controls and executes the transactions written in the data language. For example, we have the hierarchical model, the DLI language and the Information Management System. By using an unconventional approach to the design and implementation of a basic database system, we can design a system to support multiple data models and several model-based languages as if they system is a heterogeneous collection of database systems. This thesis presents a methodology for supporting hierarchical database management on an attribute-based data-base system. Specifically, we construct an interface which translates Data LanguageOne DLI calls into attribute-based language requests. The author describes the data structures, the control structures, and the functions required to implement this interface. Additional keywords Algorithms Mapping. Author.
