Minimizing transmission cost for distributed database design based on ontology schema

Along with the development of networking technology, distributed databases exist in most companies. It is important to place data in the most appropriate locations so that the efficiency of data processing can be increased and the cost of data processing can be reduced. Most recent research programs study the data allocation problems of existing distributed databases by analyzing the system operation history, such as frequency of query and data affinity. For a new distributed database system construction, a requirements analysis method based on ontology is discussed and applied to data allocation in distributed databases.
