Abstract: Using optimistic replication method, this paper proposes a new method of government information data consistency based on structure array. Distributed data storage mechanism is established. The record mode of government information data and structure array is defined. The method can support government information data which are in the distributed e-government system update and data consistency control more efficiently with lower communication and storage cost in mobile business environment.

Key words: distributed, consistency control, optimistic replication, structure array, e-government
