Performance evaluation of a temporal database management system

A prototype of a temporal database management system was built by extending Ingres It supports the temporal query language TQuel, a superset of Quel, handling four types of databases statrc, rollback, hrstorlcal and temporal A benchmark set of queries was run to study the performance of the prototype on the four types of databases We analyze the results of the benchmark, and rdentr-fy major factors that have the greatest impact on the performance of the system We also discuss several mechanisms to address the performance bottlenecks we encountered 1
