In this paper, we show a performance evaluation of distributed database in a hierarchical network in the two cases. In one case, database is managed by one supervisor agent and in the other case, it is distributed among all agents. We investigate the average expectation values of the time required by an agent to obtain a required data. In addition, how the time transition of the average expectation values of the time require by an agent to obtain a searched data in a distributed management systems changes with a queue or without queue is also analyzed.
