| Abstract: | On the basis of traditional transaction concurrent algorithm,analyzes the similarity and difference between mobile database and distributed database.It discusses timestamp agent,the base of concurrency control improved model that has gone through the change process from supporting global variable to bug transaction and basic need of all kind of application context under mobile computing environment can be met. |
