What are sequence diagrams, collaboration diagrams and
difference between them ?
Answer Posted / sid malik
A sequence diagram is dynamic interaction in time ordering but in Collaboration diagram is similar to Sequence diagram without time ordering it show the dynamic interaction in the objects. Both are called the communication or interaction diagrams. it show the objects and their association with other object in the system and tell how they communicate with each other. but in sequence diagram there is no association of objects to interacts with each other. Use sequence diagram to model flow of control by time ordering but use collaboration diagrams to model flow of control by organization. the messages passed between the objects convey the same information as sequence diagrams, but focus on object roles instead of the time sequence.
