Brief Description

This use case describes how a user logs into the Course Registration System.

Basic Flow

This use case starts when an actor wishes to log into the Course Registration System.
  1. The system requests that the actor enter his/her name and password.
  2. The actor enters his/her name and password.
  3. The system validates the entered name and password and logs the actor into the system.

Alternative Flows

Invalid Name / Password
If in the Basic Flow the actor enters an invalid name and/or password, the system displays an error message. The actor can choose to either return to the beginning of the Basic Flow or cancel the login, at which point the use case ends.




If the use case was successful, the actor is now logged into the system. If not the system state is unchanged.
