Automated Hierarchical to CODASYL (Conference on Data Systems Languages) Database Interface Schema Translator.

Abstract

An interactive hierarchical to CODASYL schema translator was designed and implemented with the goal of taking a System 2000 (hierarchical) schema as input and producing an equivalent IDMS (CODASYL) schema, storage schema (DMCL), and subschema. In addition, this system is to serve as part of an entire System 2000 to IDMS database translator system. This thesis effort includes an analysis of the hierarchical and CODASYL models, an analysis of the System 2000 implementation of the hierarchical model, an analysis of the IDMS implementation of the CODASYL model, Data Flow Diagrams for the general hierarchical to CODASYL schema translator, structure charts for the System 2000 to IDMS schema translator, translator source code, and data dictionary.
