This document presents a robust module-based database management system. It summarizes an abstract, definitions of ontology, existing systems, proposed system, and goals for developing an ontology. The proposed system introduces novel properties of robustness that allow a module-based DMS to evolve safely with respect to the schema and data of a reference DMS. It focuses on using SQL-Lite to efficiently manage large datasets. The goal of developing an ontology is to share a common understanding of information among people or software agents.
