基于XML的数据交换系统分析与设计

针对传统EDI通信时的数据交换所需的翻译软件和转换软件太昂贵的问题，提出一种以XML格式文档作为数据交换中间文档的XML／EDI架构，设计了报文类型转换、数据元转换和数据元代码转换的方法，开发出一套电子数据交换系统原型。该数据交换系统实现了异构报文类型的转换、不同数据元之间的转换和复杂编码的数据元代码之间的转换，为中小型物流企业间数据交换提供了解决方案。

System Analysis and Design of a System for Electronic Data Interchange Based on XML

Traditional EDI communication is transmitted in a closed and value-added network, and the expensive translation soft- ware and conversion software impose restrictions on the development of ED! in data exchange field. Aiming at these limitations, the pa- per presents a framework based on XML / EDI . Adopting XML technology, and using the XML document as a middle exchanged doc-ument, the authors propose the methods of packet type conversion, metadata transformation and data elements transcoding, and finally develope a prototype of an electronic data exchange system, which can be applied to the complex document format conversion of infor-mation systems in small and medium-sized logistics enterprises.
