Two sets of diagrams (models) highlight these differences.

During analysis, we create Domain Model Class diagrams (DMC). During design, using the DMCs as a foundation, we create Design Class diagrams. What information are we adding to the diagrams at this point?

During analysis, we create System Sequence diagrams. During design, using the SSDs as a foundation, we create Interaction (or design SSD) diagrams.

How are these two SSDs different?
