В DDD что такое Domain?

Every software program relates to some activity or interest of its user. That subject area to which the user applies the program is the domain of the software.

Depending on which system you’re talking about, the domain might be purchasing and procurement, or product design, or logistics and delivery. Most programmers spend their days trying to improve or automate business processes; the domain is the set of activities that those processes support.
