Due to the progress of information technology, the business market is changing its strategy for a modern online business environment. Autonomous decentralized database system (ADDS) has been proposed in order to meet the innovative e-business requirements. In case the system size increases, a multiple-agent-based coordination is proposed for achieving the timeliness property. The response time is conformed by those transactions that require coordination and those that can be satisfied immediately. In this sense, the distribution of the data in the system for coordination is a medullar issue for the improvement of the response time. A trade-off exits between these two kind of transactions depending on the capacity of allocating data among the sites and the distribution of the data and user requests in the system. A study of the trade-off and the factor that need to be considered for an allocation data technology in order to get an optimal response time is discussed.
