1.1业务用例定义关键点
-
Business use case instance – Defined above is really a specific business workflow ; that is, an instance. In reality, there are a great number of possible workflows, many of them very similar.
-
To make the use-case model understandable, similar workflows are grouped together into a business use case—a "class" in terms of the object model. To identify and describe a business use case means to identify and describe the class-like business use case, not the individual use case instances.
-
An individual a ctor – The actor is probably the real key to finding the correct business use case. Starting with individual actors—or really instances of actors—helps avoid business use cases that are too large or complex.
