Résumé
Along with the development of the economy and technology, the network has become more important in people's work and life than before. More and more people take advantage of network to improve the quality of their work and life. The network applications are based on the database visiting, and the database visiting is almost based on the Distributed database. The Distributed data service can be widely used in the corporation and many important fields. More technology and solutions are proposed, including the Mobile Agent technology. Mobile Agent is a code segment that can migration in the network, carrying the task code, using network and computers' resource, cooperating with other MAs, finishing one or more designated tasks. Compared with other mobile code, the MA technology can use less network resource, carry less information, and operate with higher efficiency. Using the technology to solve distributed problems is a hot research topic currently. In this paper, we first review the current research status in the Mobile Agent and distributed data service fields. After that, based on the current issues in the Distributed data service fields, we propose a complete solution using the Mobile Agent technology. Last, with the proposed solution, we construct a complete distributed data service model. In our solution, the traditional Distributed data-retrieving procedure is investigated and enhanced with the Mobile Agent technology to achieve high efficiency. The Mobile Agent related technology, such as MA communication, MA security, and MA cooperation technology are also used to improve the model 's efficiency and reduce the network's cost. We have used a project management system as a sub-model. Compared with the traditional approaches, the model works more efficiently with larger number of stations and large amount of the data-request. Finally, detailed analyzing of one instance is presented to show the characteristic of the model.
