Abstract

Abstract: The characteristics of data resources in seismological and geological industries are analyzed. Utilizing the data grid middleware OGSA-DAI, an XML-based heterogeneous data access and integration framework is presented, and it can provide data transparent access and fusion query. The system chooses XML as a common data model, utilizes the three-layer schema integration mechanism. XQuery is used as both the mapping language among XML schemas and the global query language, so that the global view construction and the query processing of the system are simplified.

Key words: heterogeneous data resource, data integration, data grid, schema mapping, global query

摘要： 分析地震、地质行业的数据资源特点，在数据网格中间件OGSA-DAI基础上提出一种基于XML的分布异构数据访问与集成框架，实现数据的透明访问和联合查询。系统以XML作为公共数据模型，使用三层模式集成机制，以XQuery同时作为XML模式之间的映射语言及全局查询语言，简化全局视图的构造和系统的查询处理。
