Business Entity |
A business entity
is class that is passive; that is, it does not initiate interactions on its own. A
business entity object may participate in many different business use-case realizations
and usually outlives any single interaction. In business modeling entities represent
objects that business workers access, inspect, manipulate, produce, and so on. Business
entity objects provide
the basis for sharing among business workers participating in different business use-case
realizations. |

The following workers use the business entity:
- The business designer describes it to explain a "thing" or
product in the business.
- A system analyst uses the business entities as input when describing
system use cases.
- The designer uses business entities as input for identifying entities
in the design model.

Business entities are created mainly during inception and early elaboration.
A business designer is responsible for the
integrity of the business entity, ensuring that:
- The name and brief description are explanatory.
- The responsibilities are correctly described.
- The business entity has the appropriate relationships, attributes, and operations
defined to fulfill its responsibilities.
If you are not combining business and system models, you can use the stereotype name
«entity» instead of «business entity».
If you are doing domain modeling, meaning that you identify business entities only, you
can use the stereotype «domain class» instead of «business entity».
