Abstract

A real-time database system (RTDBS} can be defined as a database system where transactions are associated with real-time constraints.In this paper, we• investigate various performance issues in a RTDBS constructed on a client-server system architecture.In a client-server database management system the whole database is stored on the server disks, and copies of database items can be cached in the client memories.We provide a detailed simulation model of a clientserver RTDBS, and present the initial results of a performance work that evaluates the effects of various workload parameters and design alternatives.
