Computer application
A computer application is a computer software program that executes on a computing device to carry out specific functions
Information system
An information system is a set of inter-related components that collects, processes, stores, and provides as output the information needed to complete business tasks
Systems analysis
Systems analysis is those activities that enable a person to understand and specify what the new system should accomplish
“What is required of the new system?”
Systems Design
Systems design consists of those activities that enable a person to define and describe in detail the system that solves a need/problem
“How does the system solve the need?”
