NDLI: A comparative study of environments for database system implementation

Content Provider	ACM Digital Library
Author	Hartson, H. Rex Fernandez, M. Teresa Suarez
Abstract	Two specific environments for implementation of experimental DataBase Management Systems (DBMS) are compared, especially in light of performance measurement: IBM 370 and HP-2100A. 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 HP-2100A 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 HP-2100A.
