基于XML技术的农产品异构数据集成研究

本文主要对如何利用Web Service技术和XML技术实现农产品物流异构数据集成进行了研究.本文首先介绍了Web Service技术的概念及其对Web数据的访问原理和对XML的支持,然后介绍了XML技术的组成、特点和XML数据模型.阐述了农产品物流技术的概念、重要性和我国农产品物流信息化的现状、问题及发展趋势.提出了面向农产品物流异构数据集成系统体系结构.在分析了现代农产品物流信息化所面临的新问题的基础上,提出了建立基于XML技术的农产品物流异构数据集成框架的基本思路,重点研究了基于XML技术的农产品物流异构数据集成框架,并对其中的数据交换中心做了进一步说明.最后介绍了S OA P技术及其信息交换模型,比较了SOAP与其他分布式对象协议的不同,阐述了传统的分布式多层Web发布系统的不足,说明了在动态Web发布中使用XML的优势,并提出了基于XML的动态Web信息发布的数据模型.本文的研究成果对农产品物流异构数据集成的实现具有一定的理论和实用价值.

Study on Heterogeneous Data Integration of Agricultural Products Based on XML

This paper mainly studies on how to use the Web Service technology and XML technology to realize heterogeneous data integration of agricultural products logistics. This paper first introduces the concept of Web Service technology with its principles of Web data access and support for XML, and introduces the composition, characteristic of XML technology and XML data model. It expounds the importance and the concept of agricultural products logistics technology, and China's current situation, problems and development trend of agricultural products logistics information, and proposes the heterogeneous data integration system architecture of agricultural products logistics. On the analysis of the new problems faced by modern agricultural products logistics information, it proposes basic ideas of the heterogeneous data integration framework based on XML technology of agricultural products logistics, focuses on the agricultural product logistics based on the technology of XML heterogeneous data integration framework, and further interprets the data exchange center. Finally, it introduces the SOAP technology and its message exchange model, compares the SOAP and other distributed object protocol,expounds the disadvantage of traditional distributed multi-layer Web publishing system and the advantages of XML in dynamic Web publishing, and puts forward thedynamic Web information based on XML data model. The research achievements of the paper has a certain theoretical and practical value for the realization of the heterogeneous data integration of agricultural products logistics.
