| With the development of network and the rapid development of computer technology, people hope that at any time, any place, access to any data demand has gradually become a reality, the embedded information system being out of the room with the traditional desktop, help the user whenever and wherever possible to obtain information, make the right decision.In mobile database, mobile transaction processing is one of the key technologies. The particularity of mobile computing environment, makes the mobile database system in the mobile transaction processing needs to be considered in traditional computing environment does not need to consider the issue, such as a mobile terminal mobility, wireless network signal connection frequent disconnection, weak connectivity and switch when the user from one region to another region. So how to solve the key technical problems of mobile transactions in mobile database technology is a very important research topic, also is the focus of this paper.In a detailed study of several typical mobile transaction processing model, this paper presents a Intelligent Mobile Transaction model, namely intelligent mobile transaction processing model (for short IMT). This model mainly includes mobile terminal transaction processing module, mobile transaction coordination module and a global transaction management module, and each module is designed in detail. Mobile terminal installation of embedded mobile database,the data on the system and the data of user query is backuped, improve the efficiency of query. At the same time in each module are introduced in the queue mechanism, for mobile transaction processing is more intelligent, smooth solution to the mobile host mobility, disconnection and area conversion problems. And in the fifth chapter, using Android simulator with the XML Web Service service to achieve a simulated IMT function of every module, it is proved that the model in mobile transaction processing is effective. |
