Title

Optimistic Concurrency Control-Schemes For Performance Enhancement.

Abstract

There are two complementary approaches to help render the optimistic approach viable. For the high-level approach, integration schemes can be utilized so that the database management system is provided with a variety of synchronization methods each of which can be applied to the appropriate class of transactions. The low-level approach seeks to increase the concurrency of the original optimistic method and improve its performance. The authors examine the latter approach and present algorithms that aim at reducing backups and improving throughput. Both single-site and distributed networks are considered. Optimistic schemes using 'timestamps' for fully duplicated and partially duplicated database networks are presented, with emphasis on performance enhancement and on reducing the overall cost of implementation.
