EDI 与 EDP 数据映射技术

Technology for Data Mapping between EDI and EDP

就电子商贸的关键技术——电子数据交换（ＥＤＩ）展开讨论，针对ＥＤＩ和电子数据处理（ＥＤＰ）的接口问题，分析了国际通用的ＵＮ／ＥＤＩＦＡＣＴ格式化数据标准，并结合ＥＤＰ应用系统的数据结构，讨论了ＥＤＩ实际应用报文的生成方法，阐述了ＥＤＩ与ＥＤＰ数据映射的工作原理，介绍了基于各种数据库管理平台的ＥＤＰ应用系统进行数据映射通用软件结构设计的思想，文中最后给出了ＥＤＩ与ＥＤＰ自动映射的软件原型系统。

Discusses the key technology of electronics commerce, electronics data interchange (EDI). Aimed at the interface between EDI and Electronics Data Processing (EDP), this paper analyzes the international standards on UN/EDIFACT (EDI for administration, commence and transport), discusses the method to generate EDI documents dealing with the data structure of EDP application systems describes the principle to map data between EDI and EDP, introduces the means to design data mapping universal software of EDP application system based on various database management platforms, and gives a software prototype to map data between EDP and EDI automatically.
