Unified Modeling Language, or UML, is a standard language for visually representing the requirements, analysis, design, and implementation of a system.
UML diagrams show structural (static), behavioral (dynamic) and implementation characteristics — and the shape and connector libraries in Gliffy make it easy. Since no single diagram can model a system completely, Gliffy's UML diagram editor makes it easy to add more diagrams as you need them. Just drag and drop from a library of shapes to show any of the nine UML diagrams needed to model a system:
A class diagram tool, sequence diagram tool, and all around free UML diagram tool all-in-one, Gliffy enables you to combine a class diagram, sequence diagram, or any combination of UML diagrams to show a design view, process view, component view, deployment view, or use case view with ease.
And since Gliffy is designed for ongoing collaborative projects, it's the perfect way to share evolving UML diagrams with your entire team.
