What is a relationship between two UML use cases?
UML use cases share different kinds of relationships. A relationship between two use cases is basically a dependency between the two use cases. Defining a relationship between two use cases is the decision of the modeler of the use case diagram. This reuse of an existing use case using different types of relationships reduces the overall effort required in defining use cases in a system. A similar reuse established using relationships, will be apparent in the other UML diagrams as well. Use case relationships can be one of the following:
What is the difference between a generalization and an extend relationship?
When you establish a generalization relationship between use cases, this implies that the parent use case can be replaced by the child use case without breaking the business flow. On the other hand, an extend relationship between use cases implies that the child use case enhances the functionality of the parent use case into a specialized functionality. The parent use case in an extend relationship cannot be replaced by the child use case.

Packages: A UML shape that allows you to put different elements into groups. Just as with component diagrams, these groupings are represented as file folders.
What is an association in a diagram?
Associations: A line between actors and use cases. In complex diagrams, it is important to know which actors are associated with which use cases. System boundary boxes: A box that sets a system scope to use cases. All use cases outside the box would be considered outside the scope of that system.

What is a successful diagram?
Goals: The end result of most use cases. A successful diagram should describe the activities and variants used to reach the goal.
