SIG框架下的空间数据中心注册服务设计

Design for the Registration Service of Spatial Data Center Based on SIG Framework

文中主要研究SIG框架下的空间数据中心注册服务,用Java语言实现空间数据中心信息的注册。注册信息以XML格式发送给服务器,服务器采用SAX解析器实时完成XML的解析,并将解析结果存储在服务器数据库中,为实现SIG框架下的空间数据中心注册提出了一种新思路。

This paper mainly researches the registration service of spatial data center based on SIG framework. With the use of Java language,the registration for the information of the spatial data center distributed over wide-area network is completed.All the information needs to be transferred to the server with XML format,while the server parses the XML file with SAX parser in real time and then deposits the whole results into the server database. This offers a new thought to the design for the registration service of spatial data center in SIG framework.
