Document Summary
There are 2 specialized uml diagrams: sequence diagram. Illustration is in a fence format, in which each new object is added to the right hand side. Clearly shows sequence or time ordering of message (strength) Forced to extend to the right when adding new objects; consumes horizontal space (weakness: communications diagram. Illustrates object interaction in a graph or a network format, objects can be placed anywhere on the diagram. Space economical flexibility to add new objects in two dimensions (strength) More difficult to see sequence of message, fewer notion options (weakness) Interaction diagrams show messages between objects; the uml has a standard syntax for these message expressions as mentioned earlier, c++, java is acceptable and supported by uml tools. : amyb : bdotwodoonedothree: amyb : b1: dotwo 2: dothreedoone return = message (parameter : paramertertype) : returntype. Parentheses are excluded if there are no parameters.
