Contemporary issues in HIM. The application layer.

Abstract

In the early years of computing, manufacturers usually sold general purpose computer systems to their customers. These systems had only a minimal set of software components. End users normally would have to work with analysts, programmers, and operators to get applications developed and executed. Personal computers, workstations, or terminals connected to larger timeshared systems, are readily available to many computer users. Multitudes of new software packages allow these employees themselves to utilize computer resources. Such packages typically are grouped together as an application layer on top of the OS. In this article, we looked at one important component of that layer--information management systems. We will look at more applications in the next two articles.
