Some examples and use cases from the internet:

• umbrello; showing a Use Case Diagram
• Use case sensitive text matching when comparing input text with contact entries
• Each Use Case leads to a relevant result (a result with business value)
• Each Use Case has an initiator (ie; an actor)
• Use case sensitive matching when comparing input data with contact data from the address book.
• Activity Diagrams are always associated to a Class, an Operation or a Use Case.
• Use Case Diagrams describe the relationships and dependencies between a group of Use Cases and the Actors participating in the process.
• Each Use Case is related to at least one actor

• Use Case Diagrams describe the relationships and dependencies between a group of Use Cases and the Actors participating in the process.
• This not only lets you view Twitters in different ways, but it introduces new use cases as well.
• Use Cases are descriptions of the typical interactions between the users of a system and the system itself. They represent the external interface of the system and specify a form of requirements of what the system has to do (remember, only what, not how).
• but it introduces new use cases as well.
• One of the first things you will do when editing a new diagram is to insert elements into them (Classes, Actors, Use Cases, & etc;) There is basically two ways of doing this:
• Associations relate two & UML; objects to each other. Normally associations are defined between two classes, but some types of associations can also exists between use cases and actors.
• When working with Use Cases, it is important to remember some simple rules:
• Use Case Diagrams show actors (people or other users of the system), use cases (the scenarios when they use the system), and their relationships
