Goal: Practice of software modeling using UML Consider the following use case specification for a use case called "Search Student" Search student Brief description: The actor receives results of students Actors: Participant Preconditions: The actor is a registered student Basic flow of events: 1. The actor logs into the system 2. The system authenticates the actor and starts a session 3. The actor chooses to search for student 4. The actor is guided by the system to fill the required criteria's to search for student 5. The actor receives results for student 6. The actor leaves the system Extensions: 1a. The system fails to authenticate the actor. • The system informs the actor and doesn't allow the actor to proceed 3a. The system fails to search • The system informs the actor Post-conditions: The system outputs results for the search of student Special requirements: Actor is connected to Internet and uses a Java enabled Mobile phone 1. Draw a class diagram for this use case (5 marks) 2. Draw a sequence diagram for this use case (5 marks)
