In recent years, grid technology, which is frequently used to solve the scientific problem, has ripened gradually. A large number of storage resources and computational power are combined to form a data grid network to deal with massive data of scientific experiments. Data replication generates huge data which are distributed in wide-area for researches around the globe. The files of grid environments can be modified by grid users might bring a critical problem of maintaining data consistency among the several replicas distributed in different machines. For that reason how to maintain the consistency of those files is a great challenge. In this paper, we propose a One-way Replica Consistency model in data grid environments, which is used for consistency maintenance issue. Furthermore, we anticipate striking a balance between improving data access performance and replica consistency in data grids. This work can find out the more efficient ways of utilizing storage space is an important point. ? 2007 IEEE.
