【Abstract】 With the improvement of mobile computing system,there is an increasing demand for many new mobile applications to process transactions in a real-time fashion.The current architecture of mobile database is no longer supporting these demands.In this paper,we propose a new architecture which can be widely used in many new fields.We also propose a multi-host cooperating method to process the real-time transaction in distributed mobile database system.Under the proposed model,the overheads for communication can be significantly reduced,and the data availability is much enhanced even under network failures.更多还原
