Solution

Q.1 Two Rules to verify and validate the functional and structural models:
Answer: 1 Each class and CRC card is associated with at least one use case.

2.There is association between the action and activities shown in the activity diagram and operations are included in class diagram.

3.The object nodes included in any activity diagram are associated with the instances of the class presented in the class diagram.

4. The Subject or object of an event in use case description is contained as association and aggregation in CRC cards.

Q 2. Two Rules to verify and validate the functional and behavioral models:
Ans. 1.There is association between communication diagram and sequence diagram and use case diagram.

2.Actors are same in communication diagram and sequence diagram and use case diagram.

3.The elements of behavioural models are related with elements of functional models.

4.All the objects included in activity diagram are shown through behavioural state machine to represent the life cycles.

Q 3. Two rules to verify and Validate the structural and behavioural models.

Ans. 1.The object included in CRUDE matrix are associated with classes included in Class diagram.

2.The objects,life cycle of which represented by behavioral state machine are included with instance of the class in class diagram.

3.Objects included in the Sequence and communication diagram are the instantiation of the classes included in class diagram.

4.The elements of behavioral models are related with elements of structural models.

5.The state included in behavioural state machine are associated with diffrent values of the set of attribute that defines the object
