Use of a Hierarchical Data Model to Support a Relational Data Management System.

Abstract

This thesis is an investigation of some of the relationships that exist between hierarchical data base organizations and relational data base organizations. It discusses these relationships in terms of the problems and solutions involved implementing a relational front end to a hierarchical data base. A solution is presented which defines all relational algebra operations in terms of hierarchical operations. The system does not have a query optimizer, but is constructed with facilities for the addition of one. It provides a vehicle which can be modified to study other relational organizations in the hierarchy.
