I need a powerful development manager like Sybase Power Designer or IBM Rational Rose that support sequence diagrams, data flow diagrams and so on.

Can somebody suggest a good alternative?

  • I change the question, cause I think it wasn't clearly describe what I need!

Dia install dia

Dia is a diagram editor that can be used to draw flow charts, UML diagrams etc.


  • I already have Gnome Dia, Is this have DFD support?

    It does have dfd support, just click on the part where it says flowchart and choose which one you want.

you can try one of these:

  • Netbeans UML plugin was abandoned in version 7. Feb 1 '13 at 17:21

Also take a look at OpenModelsphere. It is more oriented towards data modeling and can be used for both forward and reverse engineering of physical databases plus it supports a (almost) full range of UML, data modeling and business process modeling diagrams.

Oh, and its GPL v3, so no "community" versions or "non-commercial" or other "Thou shall not ..." restrictions :-)
