(1) USE Case View Include The Following:
1.USE case (case case)
2.actor (role)
3.The Communicates Relationship BetWeen Use Case and Actor (Case and Role Communication Relations)
4.The Generalize RELATION RELATIONSHIP ACTORS (Character Generalization)
5.The USE and Extend Relationship BetWeen Use Cases. (Use and Extension between Cases)
6.USE Case Diagram (Uses)
7.Sequence and Collaboration Diagram
Use copy view is equivalent to a space, and the use case diagram is equivalent to a plane, and action, use case, NOTES, the point on the plan, Relation, including Generalize, USE, Extend equivalent to the line on the surface.

Package character, use cases, classes, and components, can make a package for easy management. Package is mainly to facilitate management.
Note (Figure) is used to add instructions to use cases and characters. For example, it may be that the role interacts with that case, for a case to participate in the use or extension relationship, for a role to inherit another role
The general relationship between the role is actually the relationship between the parent class and subclasses, from the parent class to the childalize.
Use the relationship: Make a case where you can use the functionality provided by another case. Use the relationship is usually used for some two or more cases of use cases commonly used. To make a system, you must first separate those common usage cases, other cases can be used.
Extending Relationship Allows a case (optional) to extend another functionality provided by the case. It is similar to the use of relationships, and the common functions are separated into another case. For example, there is an order, delivery order, production contact order, purchase order, finished product, and so on. In fact, for the vast majority of the list, there is a single-> audit-> approval such an action. Then you can define a bill, review document, and approval documents for abstract use cases, and use Extend's Action of each contrade list.
