Notes
1. an Entity is not necessarily a physical object. It can be a Policy, a law, a contractual Condition, a motivator. These are still real for people. They have performance and Cost Attributes.
2. designers choose entities because of their Attributes. The description of the Entity is called a Design-Specification or an architectural specification, usually shortened to a design or the Architecture.
3. but if all specifications or descriptions of entities were burned, the entities themselves would continue to exist.
4. I am not sure if all entities have a Function, but it seems that they do. The Function is what the Entity does.
5. The distinction between an Entity and a System is that entities must have real existence and Systems can be imagined or Conceptual in nature.
