Collaboration diagram depicts the relationships and interactions among software. Sequence diagrams shows object interaction in timely mannerso. The difference is more in how the information is presented than in the underlying semantics of the diagram. The sequence diagram captures the time sequence of the message flow from one object to another and the collaboration diagram describes the organization of objects in a system taking part in the message flow.
