Abstract

Developing a commercial or specialized database system is an exceedingly costly and time consuming undertaking. A goal of this research is to demonstrate that a significant portion of a DBMS's software, specifically the physical database component, can be developed automatically from a small set of specifications.In this paper, we explain a new method of modeling physical databases and show that it provides a framework for realizing such a software development technology. Unlike any existing method, ours makes conceptual-to-internal mappings explicit. This enables the physical database component of operational DBMSs to be described in a systematic, precise, and simple way. Because our method also extends earlier research, it also provides a means for tieing physical database theory to practice.
