A category about the business domain, such as accounting, finance, inventory, marketing, tracking, billing, reporting, charting, taxes, etc. They tend to do a lot "tracking" and reporting (searching and summarizing) of objects and money; and generally don't model explicit activity at the physical level (such as weather prediction) except in the abstract sense (ex: "Truck X is carrying box Y"). Generally discrete mathematics is more applicable than continuous, but not in the sense above what managers and owners relate to[1]. The boundaries of the categories or "positions" are generally political (ex: district, "customer", ratings) or intellectual/legal property (ex: ownership). See CustomBusinessApplicationDefinition.

Contrast with CategoryBusiness, which addresses issues such as software pricing, management theory, etc.
