Greetings, Do UML Sequence Diagrams play a role in executable UML? I have the Mellor and Balcer book and, unless I missed something, they (sequence diagrams)...
Responding to Clemmons... ... Yes and no. In theory they are redundant if one describes behavior with object state machines and an abstract action language....
I agree. With *any* variety of UML the sequence diagrams are best used as white-board and/or tutorial tools. If your project can be specified systematically...
Hi Roy - ... I submit to you that the use of Sequence Diagrams is essential in xUML. Sequence Diagrams are used at 2 levels - the System and the Domain level -...
... The real short answer. Executable UML is the Shlaer-Mellor method using UML notation. IOW, it's been around for a long time, so it's well defined and has a...
The ideas in Executable UML are certainly compatible with everything that was in Shlaer-Mellor, but I don't think it is fair to imply that it is "just"...
