Presenting New Method to Optimize Query in Distributed Database System

Query optimization is one of the essential problems in centralized and distributed database. The data allocation to different sites is proposed in a distributed DMS(Database Management System) before a query in order to decrease, the next communicative costs namely an optimized bed production which is of ‘NP’ issues. In this article, it was attempted to examine both the methods to allocate data and produce optimized design in a distributed system and the space to query for query optimization in the distributed environment and show the need concerning optimization method in view of different aspects of optimization process. We install a new method for optimization in distributed database environment which indicates somehow our simple optimization design is executed relatively well until the database design is physical
