The MyTrip is a public service system which provides functions to a driver as follows:
A driver can plan a trip from a computer by contacting a trip-planning service on the Web.
A trip can be planned by providing a sequence of destinations and constraints (shortest way, or fastest way, or avoid passing some places, etc.)
During the planning, the driver can revise the trip by adding or removing destinations
The panning service should create the trip planning result including a sequence of segments binding a series of crossings and a list of destination
The trip will be saved with a trip name for the later retrieving through the Internet
When the driver start the car and logged in to the MyTrip system, he/she can select the trip by name to retrieve the information from the Internet
The onboard route assistant in the car obtains the trip information and guide the driver to the entire trip (like a GPS)
Do the following:
Create a domain model for the system.
Find actors and use cases and draw the use case diagrams. (follow the rules of identifying the use cases)
Write brief description for each actor and each use case. (Do not write the detail description!)
Find analysis classes for two core use cases
