在移动计算环境中，为解决移动数据库与移动终端进行数据交换的效率问题，利用移动Agent可以有效地节约网络带宽、降低网络延时、支持异步自主执行以及动态适应能力强的特点，由此提出了基于移动Agent的新型系统架构，该架构分为事务层、调度层和操作层三层；并在此基础上设计了移动数据库系统模型，该模型具备支持离线计算，实现了负载均衡等性能，解决了目前移动数据库在实际应用中存在的一些瓶颈问题。

In a mobile computing environment, in order to solve the problem with efficiency of data exchange between mobile database and mobile terminal, we use the characteristic of mobile Agent to effectively save network bandwidth, reduce network latency, support asynchronous autonomous execution and dynamic adaptability. We then put forward a mobile Agent system architecture model, in which the structure is divided into transaction layer, scheduling layer and operation layer. A mobile database system model is further designed which has the support of the off-line calculation, and is able to achieve load balancing performance and ease some bottlenecks in the mobile database applications.
