Chapter 4, Problem 4.1E
Identify and briefly describe four types of requirements that may be defined for a computer- based system.
Expert Solution & Answer
Program Plan Intro
Computer Based System:
Computer based system is a system which consists of all components necessary to capture, process, transfer, store, display, and manage information.
Explanation of Solution
Requirements of computer based system:
System requirements are generally included to communicate the functions that the system should provide. Computer based system must include the following four requirements:
- User Requirements: User requirements are statements in a natural language plus diagrams of the services the system provides and its operational constraints.
- System requirements: System requirements are structured document setting out detailed description of the system’s functions, services and operational constraints. It must define what the system needs to implement and be a part of contract between client and contractor.
- Functional requirements: Functional requirements are statement of services the system should provide and it must state how the system would react to particular input and how the system would behave in particular situations.
- Non-Functional requirements: Non functional requirements are constraints on the services or functions offered by the system. Some of these constraints are timing constraints and constraints on development process and standard and these are applied to a system not individuals.
