基于XML与RDBMS的GIS数据存取技术

An XML and RDBMS based GIS data access technology and its realization

介绍GIS(geographic information system,地理信息系统)空间数据在关系数据库中的存储方法.以shape文件为例,分析shape文件系列(*.shp,*.shx,*.dbf)的存储格式,研究在IBM DB2 9关系数据库系统中以XML(extensible markup language,可扩展标识语言)方式存储GIS空间数据的方法,实现了shape文件在DB2 9关系数据库中的存储.

This paper introduces the method of storing the GIS space data in the RDBMS. As an example, it analyzes the memory format of the shape document series （ ＊. shp, ＊. shx and ＊. dbf）,studies the method of the shape document storing in the relational database of IBM DB2 9 as XML, and realizes storing the shape document in relational database of DB2 9.
