Answer to Question 1

Use case modeling is a set of use cases that, when taken together, describe the behavior of a system. A use case is a unit of this model. It can also be defined as a contract between entities that have a stake in the outcome of a use case (i.e., stakeholders) and the system.

Answer to Question 2

An Expert system consists of:
1. User Interface the interface between the ES and the outside world. This may be an end-user interface access directly or an interface to another application.
2. Inference engine the portion of the software that contains the reasoning methods used to search the knowledge base and solve the problem.
3. Knowledge base contains the facts and data relevant to the specific problem.
