The Study Of Distributed Application System Developing Framework Based On Agent Technology

Nowdays, there are more and more requirements for developing distributed application system. An efficacious distributed system model and developing framework can improve the efficiency of the development of the distributed system and make our pruduct more dependable.Now, the most of distributed systems developments adopt the Object model, among these, the most famous technologies are: CORBA , J2EE and .NET technologies. Especially in J2EE and .NET, there are not only provide an Object model but also provid a consummate distributed system framework and many useful development tools. By studying these two technologies, we can find some useful experience which help to realize a distributed system development framework.The technology of Agent is one of the most popular Computer Information Technologies. Many researcheres study it in many fields. Now, by combinating the technology of Agent and software development, there is production of the idea of AO (Agent-Oriented) model. At the same time, there is a big progress in study of computer-aided agent designing. We find it is realizable that realizing a distributed application system developing framework through the combination of these technologies and the existed technologies of developing distributed application system. That is our idea of AT-DAS.We have developed a system like this and named it AT-DAS, which mean is the distributed application system framework based agent technology. During the experiment of AT-DAS, we have developed the core part of AT-DAS: Agent Server (AServer), which is used to agents and network management. We also have developed a kind of agent: SQLAgent, which is used to provide the SQL querying service. In order to examine our system framework, we developed a distributed arithmetic, provided the solutions of this arithmetic in J2EE, mobile agent and our AT-DAS.
