XML数据库技术在多星管控系统中的应用

Application of XML Database Technology in Multi-satellite Management and Control System

XML作为数据表示和交换的标准在信息系统的建设中得到了广泛的应用,如何使XML文档导入数据库以及如何使数据库中的数据转换为XML数据已成为亟待解决的关键问题。在研究XML文档特征的基础上,论述了2种主要的基于XML的数据库的类型及其特性。通过对多星业务管理控制系统体系结构和存储数据内容的特征分析,利用ORACLE对XML的支持机制,给出了基于XML-Enabled数据库的多星管理控制系统数据存储设计的实现方法。

XML, as the standard of data representation and exchange, has been widely applied to the construction of information systems. How to import XML document into database and transform the data of database to XML data are key problems to be solved urgently. On the basis of study on the characteristics of XML document, the main characteristics of XML-enabled database and native XML database are described. With the architecture of multi-satellite service management and control system and the features of stored data content analyzed, and with the supporting mechanism of ORACLE to XML used,the method of implementing data storage design based on XML-enabled database in multi-satellite management and control system is given.
