A Comparative Study of Environments for Database System Implementation M. Teresa Suarez Fernandez* and H. Rex Hartson Virginia Polytechnic Institute & State University Blacksburg, VA 24061 Abstract Two specific environments for implementation of experimental DataBase Management Systems (DBMS) are compared, especially in light of performance measurement: IBM 370 and HP-21OOA. The HP-2100A was selected for a skeletal implementation to study performance parameters further. The DBMS structure, some performance results, and several difficulties encountered are described. The HP2100A minicomputer did provide "hands-on" experience and more direct control to customize disk access routines. However, there were problems with performance measurement in both environments and the expected advantages of the minicomputer were not wholly realized. A specially constructed hardware timing clock would have improved the ability to measure I/O execution times in the HP2100A. I. Introduction In recent years there has been a great interest in the use of computers for specific applications in fields such as business management, medicine, law enforcement, education, and planning. The information storage and retrieval needs of these and other applications have led to the development of generalized, integrated DataBase Management Systems (DBMS). A number of DBMS models have been proposed and numerous implementations of them
