Study Of Transaction Processing Technology In Mobile Database

The development and combination of computer technology and wireless communication technology made a brand-new computing mode—mobile computing appear. Mobile computing is the result of the combination of wireless communication, network and mobile computing device and a kind of more flexible and complex distributed computing environment. It has the characters of mobility, frequent disconnection, diversity of network condition, low bandwidth, limited electrical power capacity, asymmetry of network communication and high elasticity. Just because of the above characters, the traditional database technology cannot support mobile computing effectively. Therefore, it is necessary to study new database technologies and strategies.Mobile transaction processing technology is the commanding technology and a main research trend of mobile database. In the process of study, all kinds of mobile transaction processing models have been proposed. However, every model of them has a certain shortage and they lack single standard, therefore, further study is needed.The basic knowledge of mobile database is introduced, including the critical technologies of mobile database and several existing mobile transaction processing models. Then, considering the characters of mobile computing environment, a kind of mobile transaction processing strategy is provided. The following aspects are contained in the strategy.Based on analyzing the characteristics of mobile computing environment and the shortages of existing mobile transaction processing models, this paper proposed a mobile transaction processing model and study the mobile transaction processing procedure, concurrency control strategy and resolution strategy deeply. To improve the performance and availability, the model adopts optimistic...
