Please suggest a tool to create a Domain Model diagram [closed]

Question

Could someone please suggest a tool to create a Domain Model diagram? Some details:

1. I am running Windows at the moment
2. A tool is free
3. It's not a pencil and a sheet of paper
4. It should be easy to use, i.e. I don't want to spend more than 5 minutes for a relatively simple diagram
5. I hate MS Visio. IMHO, It's ill-designed.

Answer 1

JUDE Community Edition for UML runs on Windows, is free, is not pencil and paper, easy to use (IMO), and not Visio. It meets all your criteria - try it.

Answer 2

It's not a pencil and a sheet of paper

A wacom tablet and paint.net?

It really depends what use you want for the model. If it's use to to let you understand the domain, or communicate to the guy next to you, a pen and paper are probably the best tool.

If you want to put it in a presentation, then Visio is good enough. ( For example, some of the OMG UML specs use Visio. )

If you want to perform more complicated checking and transformation ( unusual for a Domain Model ) or link it to a later implementation model, then a fully fledged model base UML tool.

IMHO, It's ill-designed.

Unfortunately, I haven't used a UML tool that was an easy to use and intuitive as I'd like ( the closest being OmniGraffle which had the ease of use for creating diagrams, but no UML model behind it ).
