![]() For instance, in an academic software that maintains records of a school or college, the functionality of being able to access the list of faculty and list of students of each grade is a domain requirement. The basic functions that a system of a specific domain must necessarily exhibit come under this category. Domain requirements engineering is a continuous process of proactively defining the requirements for all foreseeable applications to be developed in the software product line. Domain requirements can be functional or nonfunctional. Evolution qualities like testability, maintainability, extensibility, and scalability that embodied in the static structure of the software system.ĭomain requirements: Domain requirements are the requirements which are characteristic of a particular category or domain of projects. They are divided into two main categories: Execution qualities like security and usability, which are observable at run time. Functional Requirements in Software Engineering are also called Functional Specification. There are many ways of expressing functional requirements e.g., natural language, a structured or formatted language with no rigorous syntax and formal specification language with proper syntax. In order to accurately describe the functional requirements, all scenarios must be enumerated. Each high-level functional requirement may involve several interactions or dialogues between the system and the outside world. For example, in a hospital management system, a doctor should be able to retrieve the information of his patients. ![]() They are basically the requirements stated by the user which one can see directly in the final product, unlike the non-functional requirements. These are represented or stated in the form of input to be given to the system, the operation performed and the output expected. All these functionalities need to be necessarily incorporated into the system as a part of the contract. It can be a calculation, data manipulation, business process, user interaction, or any other specific functionality which defines what function a system is likely to perform. Can be customized to match your business. Advantages: Less expensive than designing the same application from scratch. Examples: SAP, SalesLogix, inventory, and accounting packages. Cost: Can be expensive with installation costs and service plans.
