With the rapid development of network technology and the frequent use in our working life, enabling users to unlimited use of mobile terminals to connect distributed mobile database, it caused connectivity, anytime, anywhere mobile data transaction processing in a mobile distributed synchronization Database facing new problems, and therefore the existing mobile database technology to make changes to create a fully database technology to meet customer needs. Mobile database, mobile transaction processing is an important key technologies, it is mainly used to maintain data consistency, support for concurrent access, to meet the needs of multiple users to maintain a fixed range of users can maintain a continuous link mobile database. Mobile database systems also have to provide these services to meet the needs of mobile applications. Special nature of mobile computing environment for mobile database design than ordinary database with the application of this aspect with more complex requirements such as client mobility, frequent disconnection, weak connectivity, over-area switch and so on. So how to solve the mobile services of these key technical issues, so the server to complete the treatment of mobile services, mobile database technology to become a very important research topic.Mobile Agent offers a new distributed computing model to distributed system design, implementation and maintenance have brought many benefits, this paper, the characteristics and objectives of the mobile database, mobile Agent technology applied in the study which focused on the data consistency problems of the Agent composition, Agent interaction between the data and proposed an improved algorithm for mobile Agent. Detailed design of the Mobile Agent Communication Agent positioning, messaging and migration of the communication process, the algorithm to ensure efficient transfer Agent on the basis of information to solve the issue of communication failure between the multi-Agent. Mobile Agent in Mobile combines the advantages of the database, as well as a series of programs on the Agent’s cache, considering in the process of combining a variety of problems may well occur. Agent established in the mobile database cache architecture. For existing mobile database was improved. Up before optimization and transaction processing in data consistency issues
