| 摘 要： | XML已经成为事实上的数据表示和数据交换的标准,越来越多地应用在数据交换和存储领域。NXD是专门设计用于存储XML数据的数据库,其特点是以XML数据自身的形式来存储XML数据;XQuery查询语使得不同的XML数据管理系统能够以统一的方式向用户提供访问接口。本文基于以上XML存储管理技术,实现了GML本原存储,深化研究并拓展了基于XQuery的地理空间数据查询语言,实现对GML地理空间数据的本原查询。

| Abstract: | XML has become the defacto standards of data expression and data exchange,it is more and more used in the field of data exchange and storage.NXD is designed to store XML data in the database,which is characterized by its own form of XML data to store XML data;XQuery query language allows different XML data management system in a uniform manner to provide interfaces for users.Based on the XML storage management technology,we have achieved native GML storage,deepened and expanded the study of spatial data based on XQuery query language,which is used to achieve native query for GML spatial data. |
