中文摘要：

文章采用移动代理技术实现了对数据库的远程访问。与传统的基于Client／Server计算模式相比，在涉及到必须对大量远程数据进行处理时，基于移动代理Aglets平台的远程数据库访问技术能够明显的提高通信效率、改善系统性能。此外，通过对移动代理携带的结果数据引入消息摘要和加、解密技术，数据的安全性也得到了极大的提高。实验结果显示，文章中实现的基于移动代理的远程数据库访问技术是安全、可行的，特别在应用涉及对大量远程数据进行处理时，该技术比Client／Server计算模式有明显的性能优势。

英文摘要：

This paper adopts mobile agent technology to achieve remote access to databases. Compared to the traditional Client/Server computing model, this method can significantly improve the communication efficiency and system performance when a large number of data located at remote sites must be handled. In addition, the security of data can be enhanced to some extent by using message digest, encryption and decryption techniques on the results carried by mobile agents. The experimental result shows that this access method for remote databases based on mobile agents is security and feasible. Especially to a large number of remote data processing, this technology gets more advantages over the Client / Server computing model in the aspect of performance.
