In software engineering, domain knowledge is awareness of the environment in which the target system operates. It is important because that usually must be learned from end-users in the domain (as domain specialists or experts), rather than from software developers.

A Domain is nothing but core knowledge of any particular sector, specific industry, or nature of business. In simple words, we can say, a particular area of work or specific area to be worked upon.
