The subject area to which the user applies a program is the domain of the software. An area of interest or an area over which a person has control It is all about grouping concepts. Within Domain-Driven Design we call the entire problem space we are modelling the Domain. We decompose that space into several subdomains. If the space is big enough those subdomains can be potentially split into several subdomains again. AKA Domain Modelling
