We propose Colored Petri Net (CPN) models for replicated and centralized database systems and conduct a comparative study of their performance. The designed CPN models capture the dynamics of the studied database systems and estimate their expected performance with an appropriate level of abstraction. A number of simulation experiments were performed under various load conditions of varying parameters such as server speed, network speed, and read/write ratio. The simulation results show that under similar operation conditions, replicated systems exhibit higher performance than centralized systems in terms of query response time and system saturation levels. However, centralized systems become more competitive when their network and server speeds are much higher than those of the replicated systems.
