基于XML的粮食储备库异构信息集成平台设计
THE DESIGN OF HETEROGENEOUS INFORMATION INTEGRATED PLATFORM IN CENTRAL GRAIN DEPOT BASED ON XML
【摘要】 随着信息化技术的普及与发展,早期所使用的各种粮食信息由于其数据具有海量性、多源性、空间性、时间性、形式多样性等特点,使得粮食信息共享成为一个难题.本文提出一个基于XML技术的异构信息系统数据集成框架,以XML统一的信息描述标准去定义各种数据源中的数据,使实现异构数据源的信息集成与信息平台的查询和检索等数据互访成为可能.
【Abstract】 With the full use of the information technology and the popularization of the commucations of the network information,various grain information used in the past make the sharing of grain information difficult because of its data characteristics such as abundance,multi-source,timeliness,extensity,diversity and so on.Data integration frame of hetero-structural information system based on XML technology was pointed out,and data in various kinds of data sources were defined with uniform XML standard.This made the query and retrieval,and exchange of data of hetero-structure possible,and also provided a theoretic foundation to construct the information integration system.
【Key words】 grain information; database of hetero-structure; XML; information sharing;
