| 摘 要： | 随着信息技术的发展,所管理的数据也发生着重大的变化,从过去仅仅管理结构化数据,至今必须管理多种类型的非结构化数据。这一变化给数据管理带来了挑战。元数据在避免数据的重复性建设以及协调不同数据部门之间的资源共享中发挥着重要的作用,智能代理通过具有一定智能性的搜索策略建模,实现对元数据库的快速检索、数据的快速下载、数据的交互预览和信息缓存机制。同时讨论了基于元数据技术和智能代理技术的“数字成都”数据管理方案。

| Abstract: | The data management has changed enormously as companying with the development of the Information technology. It changed from structured data management to non-structured data management. This change leads to many new problems and challenges. Metadata works importantly in information sharing system. Metadata can avoid the repeatedly data construction and conform information sharing between different data supply departments. The information mining technology based on agent was proposed, and the integrated data management was designed and developed. With the help of intelligent search tactics modeling, the quick search of metadata base, the quick download of the data, the mutual preview of the data and information cache were realized. In this paper, we discuss the data management in digital Chengdu based on metadata and intelligent agent. |
