Watch out for closed or product specific code generation processes or frameworks as you could end up stuck with that product. Sparx and Visual Paradigm do UML really well and generate code well, however, hooking into project lifecycles and other process is where RSM/RSA is strong. Ok, that was way too detailed, so a simpler example would be ArgoUML, which has no code generation features and focuses on drawing more than the modeling aspect of UML. Do you need more mature processes such as use case management, pattern creation, asset creation, RUP integration, etc? (RSA/RSM/IBM Rational Products)ĭetailed Examples: IBM Rational Software Architect did not implement UML 2.0 all the way when it comes to realizes type relationships when creating a UML profile, but Visual Paradigm and Sparx got it right.Would you want to generate code stubs or full functioning code?( GenMyModel, Visual Paradigm, Sparx, Altova).Do you have an existing set of documents that you need to work with? (Depends on the documents).Are you concerned about model portability, XMI support? ( GenMyModel, Sparx, Visual Paradigm, Altova).Do you want to formalize your modeling through profiles or meta-models? OCL? ( Sparx, RSM, Visual Paradigm).Will you be modeling in the future? (For basic modeling - Community editions of pay products).Are you modeling or drawing? (Drawing - ArgoUML, free implementations, and Visio).Note: The listed answers are my view as the best even if other products support a given feature or need. Here are the questions that should be answered as each vendor product/solution does some things better than others.

Sure, diagrams are important, but really you are creating a model. A common misunderstanding is that UML is about creating diagrams. The previous posts have too many answers and not enough questions.

Dessinez vos propres diagrammes avec vos propres formes.Some context: Recently for graduate school I researched UML tools for usability and UML comprehension in general for an independent project.

Différentes options de formatage (forme et lignes, peinture pleine et dégradée), plus de 40 types de connecteurs, légende RTF, options de police, effet d'ombre, etc.

Les connecteurs sont collés aux formes et ne se séparent jamais. Facile à utiliser: créez et connectez des formes par glisser-déposer.
