Abstract:This paper presents a multijoin algorithm for query optimization in DDBS, which takes minimization of response time as the criterion of optimization and transforms multijoin into two way joins in a relatively optimal way. The algorithm takes both the communication costs and the local processing costs into account.
Keywords:distributed database  query optimization  multijoin  semi-join
