What is the difference between Join and Merge in Unified Modeling Language Activity Diagram. Give an example to understand more clearly. Join Node (see reference 1 ): Join node is a control node that has multiple incoming edges and one outgoing edge and is used to synchronize incoming concurrent flows . Join nodes are introduced to support parallelism in activities . Merge Node (see reference 2 ): Merge node is a control node that brings together multiple incoming alternate flows to accept single outgoing flow. There is no joining of tokens. Merge should not be used to synchronize concurrent

I am looking out for a eclipse plugin or an open source tool to reverse engineer the sequence diagrams. I tried using Alto UML, but it just gives out sequence diagram of the class chose. I would like to have a sequence diagram of the whole call stack with methods, input arguments and output arugments as well. Could you please let me know some pointers on this? Thanks! Jordi Cabot Take a look at the MoDisco open source eclipse project MoDisco Architexa does have sequence diagrams for the whole call stack with methods. What you will find is that unlike typical UML tools Architexa is much more

How is it possible to use parts of the C++ STL in Enterprise Architect? It would be nice to be able to specify certain class attributes as std::string or use std::auto_ptr (or even std::tr1::shared_ptr ) as types. Another interesting thing would be how one is able to integrate container-types like std::vector and std::map into EA. Gabor Herman I have taught how STL containers look like to EA, I guess it can be extended to stl pointers too: Forward engineering: You can define collection classes for different multiplicities globally in the language settings, or for a specific class of your

While I think I understand aggregation and composition , I am having difficulties understanding bi-directional and uni-directional association. I've read that with bi-directional association, both classes know about each other and with uni-directional association only one of the classes is aware of the relationship. However this explanation seems too abstract for me and I would like to know what this in particular means for my code and for the program I am writing. It would be very nice if you could, along with explanation, provide a simple example of how these two translate to code (I prefer

I'd like to try UML2 Tools for Eclipse, as shown in this tutorial . I currently have Eclipse 3.6 Helios for Java EE developers. In my Eclipse Marketplace I switched marketplace catalog to Yoxos Marketplace and there searched for UML2 Tools SDK(Incubation) . When I try to install them, Eclipse wont proceed and complains about some conflicting dependencies. Here's whole trace: Cannot complete the install because of a conflicting dependency. Software being installed: UML2 Tools SDK (Incubation) 0.9.0.v200906190654 (org.eclipse.uml2tools.sdk.feature.group 0.9.0.v200906190654) Software currently

This question is related to diagraming a software process. As an electrical engineer, much of the software I do is for embedded micro-controllers. In school, we learned to illustrate our algorithm using a flowchart. However, nowadays, many of my embedded projects are heavily interrupt-driven where the main process runs some basic algorithm a variety of interrupt sources provide its stimulus. So, my question is, what are some diagramming techniques that I can use to illustrate my process such that future developers can understand what I am doing easily and get involved in development? Here are

What symbol should I use ? Below is an extract from the Unified Modeling Language specification. The complete specification is available at http://www.omg.org/spec/UML/2.3 . 9.5.1 Comment A comment is a textual annotation that can be attached to a set of elements. Description A comment gives the ability to attach various remarks to elements. A comment carries no semantic force, but may contain information that is useful to a modeler. A comment may be owned by any element. Notation A Comment is shown as a rectangle with the upper right corner bent (this is also known as a “note symbol”). The
