Instructions

You will create an architectual specification of the Traffic Problem using Class and State Diagrams according to the UML notation. You will use Argo/UML to draw the diagrams. Please refer to the UML Distilled or Schach text to clarify the syntax and semantics of the diagrams requested below. The specifications document will consist of the following.

1. Title Page.
• name
• student id
• date
• assignment name
2. Summary. A two page summary of the contents of the specification document:
• Which apects of the use cases/scenarios (see below) are being specified?
• Are there exceptions, problems, special considerations in understand any of the specification diagrams that follow?
• Are there special conditions for testing any aspects of the system specificied?
3. Use Cases.
• Repeat use case diagrams from Assignment 4 that you are choosing to further specify in this document.
• You do not need to repeat them all, only the ones that you will be refining specifications for.
• Please repeat the textual descriptions for these as well!
4. Class Diagrams. Identify about 12-15 classes that are relevant to one or more of the use cases you developed in Assignment 4.
• Draw one or more class diagrams to illustrate and specify the class interactions.
• On a separate page, write a one-sentence description of each class, association, attribute, and operation.
• Indicate which use case(s) a class diagram pertains to.
5. State Diagrams.
For two of the classes above, draw state diagrams to illustrate potential changes in states over the possible course of interactions.
• Each state diagram should have several activities (states) and actions (transitions).
• As appropriate, label the state transitions with guards (see below).
6. Test Cases. You will specify more detailed test cases in this assignment. Think in terms of planning for system and unit testing. Specifically attend to the following.
   • Be certain that the attributes in the classes have a type identified. If you need to specify a new type be sure it is defined somehow in your document.
   • Be certain that the class associations are labelled with their cardinality.
   • Label transitions with guard conditions as appropriate. You can expect more than half of all transitions to have guards.
