The UML diagrams are simply layout documents which help to satisfy the design by contract and to refactor code taking advantage of the AST. State transition diagrams can be derived from activity diagrams : a state is an assertion, a transition is an activityīut in the end, the UML model is directly the code.a=9 where ‘a’ is the subject, ‘equals’ is the property and ‘9’ is the object) An assertion is or a semantic triple (e.g.A simple activity can be formally defined as a single assertion.A complex activity is detailed by another activity diagram.Human operations should also be described in the activity diagrams.Adding a log message with an appropriate level for each activity / method is really helpful for debugging.An activity is a method belonging to a class for each activity non-human.This can be done if and only if activities are enhanced with formal preconditions and postconditions assertions (on the code side, exceptions management is properly set up).The software whole development process could be done with only two kinds of UML diagrams : a behavioral and a structural diagram, e.I personally started a few years ago the Coffea plugin as a personal project in 2007 project but do not have the time to make it evolve. As a Frenchman, I understand the reasons why the eclipse foundation partners focus on the Papyrus project, but I really miss the UML2 tools development. These tools could be really enhanced to provide very interesting refactoring operations. Two projects, Green UML ant Coffea UML, take advantage of the Eclipse platform to do such a job. This structure is sufficient in languages such as Java or C# to set up the elements of UML class diagrams. Compiled programming languages (sorry for scripts enthusiasts) provide a clear structure of an object-oriented code (the AST).Modelio is an idea of a development tool. I have to confess I am personally included in this population. Most object-oriented programmers don’t really take care of the design by contract.UML is widely used for code generation on large projects. In software development, many developers find the UML diagrams difficult to conceive and maintain while writing code.I consider this subject important for two personal opinions : What is a legacy software ? In my point of view, a software not documented at all, not properly conceived taking advantage of most common design patterns.Īs a consequence of my daily work, I consider round-tripping pratices as a very important topic but don’t know until now an insteresting sollution. ![]() ![]() In my daily tasks, I rarely develop clear and fresh applications and mainly maintain legacy software.
