一种基于XML数据模型的时空查询代数探讨
Spatio-temporal Query Algebra Based on XML Data Model
摘要
Abstract
The spatio-temporal query algebra is one kind of abstract spatio-temporal query language; it uses the subset of basic predicates, operations, the functions of spatio-temporal abstract data type to express the spatio-temporal query. While the data model of the spatio-temporal microscopic operates employed the XML data model which the Native XML Database (NXD) adopt to store semi-structured spa-tial-temporal data, therefore this article held the space and time expansion to the XML query algebra - Xquery FS data type and the query, and introduced in GML to describe the geography feature and if s relationships, has defined one kind newly based on the XML data model space and time inquiry algebra.关键词
