基于移动Agent的分布式数据访问模型

Data accessing model for distributed application based on mobile Agent

移动Agent技术为人们提供了更加统一的处理分布式系统中的代码和数据的解决方案,“代码移向数据”是移动Agent技术的重要思想.研究了Agent技术,并结合Java体系的RMI机制,讨论了一种Agent技术与分布式对象相结合的分布式数据访问模型,并基于此模型实现了一个分布式数据查询系统.在局域网上进行了试验,并与分布式对象技术做了比较,取得了较为满意的效果,展现出了良好的应用前景和优越性.

Mobile agent technology that moves code to data site provides a more unified scheme to disposal the code and the data in distributed system. We designed a data accessing model which integrates the agent technique and distributed object-oriented technology with java RMI mechanism. According to the model, distributed data query system on LAN environment had been realized. Finally, the model has been experimented on the LAN, and obtained approving effect compared with distributed object technology. This kind of application has good praspect and superior performance.
