In software engineering and other computing disciplines, the domain of application (or domain of application, in some cases domain of the problem) refers to the context in which a software application operates, especially with regard to nature and meaning of the information that needs to be manipulated. In the most popular models and software development methods, domain analysis (ie analysis to understand the operational context in which the application is to be included) is an essential (and generally preliminary) component of the requirements analysis .
