Behaviour modelling
- 1. UML DYNAMIC MODELING(BEHAVIOR DIAGRAM)
- 2. UML DYNAMIC MODELING(BEHAVIOR DIAGRAM) It helps in visualizing what should happen in system. It show how two different object interact for the functionality of system. It show how message is passed between objects.
- 3. DIAGRAMS USED TO EXPRESS DYNAMIC SEMANTIC OF A PROBLEM • INTERACTION DIAGRAM SEQUENCE DIAGRAM COLLABORATION DIAGRAM • STATECHART DIAGRAM • ACTIVITY DIAGRAM
- 4. UML INTERACTION DIAGRAM • It is used to capture the interaction of different object • It show how groups of object collaborate to get the job done. • The main guideline in developing interaction diagram is simplicity.
- 5. PURPOSE OF INTERACTION DIAGRAM • To capture dynamic behaviour of a system. • To describe the message flow in the system. • To describe structural organization of the objects. • To describe interaction among objects.
- 6. SEQUENCE DIAGRAM • It is used to capture the sequence of interaction between object • It show object participating in the interaction by their lifeline and the message they exchange in time sequence • It show overall flow of control of a program • It has two dimension • vertical dimension represents time whereas horizontal dimension represents object • Objects are in box whereas message are shown by arrow between lifelines.
- 7. EXAMPLE
- 8. COLLABORATION DIAGRAM • The second interaction diagram • It is similar as sequence diagram • Here objects are placed in box and timing sequence is described using number technique. • Sequence diagram doesn't describe the object organization where as collaboration does.
- 9. DISADVANTAGES • It is great only for representing a single sequence process • It breakdown when you want to represent condition looping behavior
