摘要 随着网络技术的发展,分布式数据库应用越来越广泛。将数据存储在合适的位置不但能够提高数据处理的效率,而且能够减少数据处理的成本。近来的大多数研究都侧重于已存在的数据库,通过分析系统操作历史来研究数据分配问题。论文提出一种基于本体模式的分布式数据库系统构造及需求分析方法,用于解决分布式数据库的数据分配问题。 With the development of networking technology,the applications of distributed database become more and more popular.If the data is placed in the most appropriate locations,the efficiency of data processing will be increased and the cost of data processing will be reduced.Most of recent researches study the data allocation problems of the existent distributed databases by analyzing the system operation history.This paper proposes a new distributed database system construction and requirement analyses method based on ontology,and applies it to data allocation in distributed databases.
