前面,我们用三讲的篇幅论述了计算机网络,它是系统集成的基础构件。下面,我们开始介绍应用软件(application software),它是系统集成的核心。从具体工程或项目的角度看,系统集成是一个过程:它把不同厂家的硬件产品和软件(食购置的、剪裁生成的及特制的)结合起来,以专业服务的方式为特定用户提供整套实用的计算机系统。这里的核心问题是为特定用户服务。也就是说,要注意体察和体现个性差异,这是系统集成商对用户负责的表现。这副重担责无旁贷地落在了应用软件的肩上,因为用户正是通过应用软件的界面来认识和操作整个计算机系统的。
In front, we discussed the computer network in three parts, which is the basic component of system integration. Below, we begin to introduce the application software (application software), which is the core of system integration. From a project or project perspective, system integration is a process that combines hardware products and software from different vendors (purchased, tailored and tailor-made) to provide a complete set of practical, user- Computer system. The core issue here is to serve specific users. In other words, pay attention to reflect and reflect the personality differences, which is the system integrators responsible for the performance of the user. This subordinate is entirely on the shoulders of the application software, because the user is through the application of the software interface to recognize and operate the entire computer system.
