以下对信息系统集成的描述正确的是()

A.信息系统集成的根本出发点是实现各个分立子系统的整合

B.信息系统集成的最终交付物是若干分立的产品

C.信息系统集成的核心是软件

D.先进技术是信息系统集成项目成功实施的保障

答案

参考答案:C

解析:信息系统集成是近年来国际信息服务业中发展势头最猛的服务方式和行业之一。系统集成是指将计算机软件、硬件、网络通信等技术和产品集成为能够满足用户特定需求的信息系统,包括策划、设计、开发、实施、服务及保障。信息系统集成有以下几个显著特点:①信息系统集成要以满足用户需求为根本出发点。②信息系统集成不只是设备选择和供应,更重要的它是具有高技术含量的工程过程,要面向用户需求提供全面解决方案,其核心是软件。③系统集成的最终交付物是一个完整的系统而不是一个分立的产品。④系统集成包括技术、管理和商务等各项工作,是一项综合性的系统工程,技术是系统集成工作的核心,管理和商务活动是项目成功实施的保障。可见,"信息系统集成的核心是软件"这一叙述是正确的,其他选项的叙述均不正确,故应选择C。
