Abstract
In this paper we prescribe a replication server scheme with an algorithm DRF (Differential Refresh
File) to refresh multiple materialized views and replicas in distributed environments. Before
sending relevant tuples in server sites to client sites, an effective tuple reduction scheme is developed
as a preprocessor to reduce the transmission cost. Because it utilizes differential files without
touching base relations, the DRF scheme can help to minimize the number of lucks, which
enhances the system's performance.
