Collaboration Diagram Vs Sequence Diagram. In order to show time ordering you must indicate a sequence number and describe the message. In uml the two types of interaction diagrams are collaboration and sequence diagrams.
The differences between timing diagram and sequence diagram are the axes are reversed so that the time are increase from left to right and the lifelines are shown in separate compartments arranged vertically. Because of the format of the collaboration diagram they tend to better suited for analysis activities see activity. Just the difference is that the lifeline does not consist of tails.
On other hand collaboration diagram is a diagram in which main representation is of how one object is.
Both the sequence and collaboration diagrams represent the same information but the way of portraying it quite different. The diagram captures the behavior of a single use case. Sequence diagram is used for the purpose of dynamic modelling. Both the sequence and collaboration diagrams represent the same information but the way of portraying it quite different.
