uml

hi every body i'm trying to understand UML but there are some questions about it In UML what is the significance of tagging a class with the stereotype <<abstract>> ? and how to express this constraint as an invariant, A stereotype "abstract" does not exist - an abstract class should be depicted using italic font. Abstract means that a class cannot be instantiated. It needs a subclass to do so. So as a pseudo-code constraint this would mean for all instances i of MyAbstractClass holds: i.actualClass != MyAbstractClass or in ocl for MyAbstractClass holds self.allInstances()->forAll(i:

The classes should have individual features like color or type size. Therefore I am going to adapt the code to my requirements. I've already come across Raphael and Umlcanvas. Are there any other libraries? Which one should I pick? Thx in advance for help! 回答1: There are many tools that will transform a textual description of a uml model into a graphical representation (see here for a

Consider an example of a company and employees. Two valid class diagrams are: Now let's try to draw the corresponding object diagrams: If the details of the fulltime_employees like age are important,

I want to have a correct use case diagram for an online job portal system. Here is my attemp: I have some doubts: I can't see where making "Login" use case witch is an important use case for this system. This use case diagram is not showing the difference between a simple visitor and a registered one. The former could view vacancies, view advice without the obligation for having an account. The latter could view vacancies, view advice, upload CV (after be logged), apply for a job (after be logged) ... Is having two actors "Simple visitor" and "Registred Visitor" in my diagram will be correct?

How can I do this? 回答1: It can be worth to give a try to the XMI file converter its web based using Php. 回答2: If RSA won't import XMI 1.1 then you'll need to find another tool that will. Enterprise Architect by Sparx Systems can import XMI 1.1 and can write XMI 2.1. You can get a free 30 day trial from their website at http://www.sparxsystems.com . Be warned though that there are

I need to maintain some project in Java, but it is very big. I need some plugin for Eclipse or program alone which can generate UML from Java project. Is there something what can help me ? Visual Paradigm for UML Tools --> Instant Reverse --> Java --> Specify your sources and you are done. This is a commercial application with lots of stuff, but for what you need to do, you are fine with the evaluation key. EDIT: Also have a look at this video Ratna Dinakar This has been asked before.. please find it at How to generate UML diagrams (especially sequence diagrams) from Java code I recommend
