Research on Data Allocation in the Distributed Database Based on Instances
Jiangjiao Duan · Journal of Xiamen University · 2002
Well-designed data allocating contributes greatly to data usability, improving efficiency and reliability of DDB. In this paper, we discuss the principles of data allocating by instances, and research data allocation such as non-redundance allocating, redundance allocating, static and heuristic allocating by quantitive method. Also, there are some comparative analyses of dynamic allocating. During research process, considering distributed search and updating problem, we achieves optimum settlement by reducing cost of transportation, search and updating. Thus, we define the best place of logic segments after divided from global relation.
