A Personal Assistant for Web Database Caching

To improve the performance of web database access for regular users, we have developed a client caching agent, referred to as a personal assistant. In addition to caching strategies based on data characteristics and user specification, the personal assistant dynamically prefetches information based on previously monitored user access patterns. It is part of an overall multi-layered caching scheme where cache coherency is ensured through cooperation with a server-side database caching agent. The personal assistant has been implemented in Java and integrated into the web architecture for the OMS Pro database management system.
