QuickUML is a software design tool that tightly integrates a core set of UML models with code generation for several languages. An entire project is presented through a tabbed window that includes use cases class models object models dictionary and code and saved as an XML file. Use cases document user interactions with the system and link to models code foreign files or other use cases. Class models may contain classes interfaces components packages and other objects. Sequence diagrams illustrate how objects interact with emphasis on the order in which things occur. QuickUML contains advanced features for multiple language projects design namespaces UML stereotype extensions flexible color support custom detail fields and automated generation of class models from the dictionary. An integrated code manager enables the designer to navigate through code files linked to use cases and diagram objects.
