电子数据交换(EDI)涉及到的三个主要技术任务是 (44) 。EDI的标准有多种,其中较为典型的是美国国家标准局制定的X.12标准,以及联合国支持制定的 (45) 标准,通过计算机处理,这两种标准之间可以互相转换。

A.EDIFACT

B.SET

C.S/MIME

D.PEM-MIME

答案

参考答案:A

解析:

[分析]: EDI涉及到的三个主要技术任务是单证(数据)标准化、通信网络建设和应用系统开发。单证标准化的主要目标是统一单证中的数据元和纸面格式,内容相当广泛。计算机网络通信是EDI得以实现的必备条件,EDI通信标准则是顺利传输以EDI方式发送或接收的数据的基本保证。EDI的应用系统主要是一些翻译软件,即把用户的格式翻译成单证标准格式。
国际上,20世纪60年代起就研究EDI标准。1987年,联合国欧洲经济委员会综合了经过10多年实践的美国ANSI X.12系列标准和欧洲流行的“贸易数据交换(TDI)”标准,制定了用于行政、商业和运输的电子数据交换标准(EDI FACT)。该标准的特点,一是包含了贸易中所需的各类信息代码,适用范围较广;二是包括了报文、数据元、复合数据元、数据段、语法等,内容较完整;三是可以根据自己需要进行扩充,应用比较灵活;四是适用于各类计算机和通讯网络。因此,该标准应用广泛。
