摘要

参考当前元数据技术及相关标准，探讨了官厅密云水库上游水土保持监测系统信息平台建设中。元数据的构建与实现。首先针对应用系统建设的实际需求，明确了信息平台建设所包括的元数据内容：基础元数据与业务元数据，并描述了两者内容及其应用目标；其次在数据库技术支持下说明了元数据组织存储模式、结构关系等；最后说明了元数据的实现方式，并提出了元数据与数据同步、一体化管理，在信息平台数据更新维护的基础上实现了元数据的同步更新，从而集数据库及其元数据的更新维护于一体，实现了信息平台的有机构成。

Abstract

The objective of the paper was to expound the main process of metadata technology and method applied in the construction of soil and water monitoring information system. Firstly the paper defined contents of rectadata

including basic metadata and business metadata

among of them

the basic metadata were used to manage the data stored in the database and mainly to describe the information about data

and the business metadata helped system to implement the function of update and inquiry of data. Secondly the paper expounded in details contents and purposes of two types of metadata and described how to organize and store these metadata. Finally

the flow chart of management of metadata was proposed

and functions of creation and management of metadata were integrated into the management and update system for information platform

then the synchronous management for metadata and their data was realized for the system.
