Examine about the Behavioural Diagrams
The main objective of behavioural diagrams is to visualize, specify, construct and document dynamic aspects of a system. The interaction among objects indicating flow of control between them is shown using these diagrams. The flow of control can encompass a simple, sequential thread from a system, as well as complex flows which involves branching, looping, concurrency and recursion. They could model sequence of messages (collaboration diagram) or time ordering (sequence diagram). The four major behavioural diagrams are: use case, activity, interaction and state chart diagram.
