Agent-based Mobile Database Key Technology Research

With the rapid development of computer network technology, mobile computing is becoming the focus and hot spot of competition in the industry. In the Advantages of computer technology, mobile computing technology is one of the fastest growing areas of mobile computing. It's a new technology that allows a computer or other computing devices can be fixed without a physical device connected with the case of data transmission. The role of mobile computing system is to integrate with the useful, accurate, timely information and interaction between the central information system. And it can share the calculation of pressure of the central information system, so that the information can be provided to its users at any time, any place, any need. In the past decade, the new computing model had a rapid development and a growing number of applications to play an irreplaceable role. We can predict that the future of mobile computing technology will become an important member of the information age and have a profound impact of people using information.This article will integratedly descripte and analyze the basic theory and techniques which used in mobile database, mainly referred to three aspects ,that are the mobile transaction processing technology, mobile database replication technologies and mobile data broadcasting. These three technologies are the mobile database for processing the key. First, we discuss the mobile transaction processing technology, focused on the current model of typical mobile services. Second, for mobile data replication technology, mainly mobile replication concepts and key techniques are analyzed, and it proposes a new mobile replication model: transaction-level results set to pass (TLRSP) mobile database replication model, so as to move the database replication technology provides a practical solution. Finally, the concept of data broadcasting and key technologies are discussed.Mobile Agent offers a new distributed computing model, which bring many benefits to distributed systems design, implementation and maintenance.From the analysis of the basic functions of Mobile Agent System starting in the mobile database and mobile Agent technology for in-depth study, based on the design of a simple e-commerce applications Mobile Agent System, combined the characteristics and objectives of the mobile database in Mobile Agent technology, focused on the mobile Agent system architecture, key technologies, and Mobile Agent security and organization for Standardization and regulatory issues, and evaluated the current market of several typical systems,then outlines the application of functional requirements, design system framework, and application system-related technical issues involved in detailed analysis and discussion.
