IRAIN - an instructional relational database system designed for small computer system

摘要

A modular design approach for a database system is presented in this paper. We require that every database file be self-descriptive and every program module be self-contained. To improve access efficiency and database security, database decomposition is also considered. Based upon this approach, IRAIN - a relational database system is designed and implemented on PDP11 UNIX system. Similar approach can be applied to other data models.
