Any element can be exportedas a fragment, but typically UMLPackage, UMLModel, and UMLSubsystem are the candidates. If the name of a model element changed, all correspondingview elements reflect the changes in their diagrams.Ī fragment is a part of a project saved as a separate file with the extension name. View elements mayexists multiple times in a diagram or in different diagrams. A view element just renders the corresponding model element in a diagram. A model element has its own data such as name,stereotype, type, etc. Diagrams consists of view elements, which are visualrepresentations of a model element.Ī model element typically has multiple corresponding view elements. For example, a diagram can focus on class hierarchical structurewhile another diagram can focus on interaction between objects. A software model can be representedin one or more diagrams with different aspects. A Model element is a buildingblock of a software model.Ī Diagram is a visual geometric symbolic representation of a software model. A software model can be represented in textual, mathmatical or visual form. Model or software model is a description of any aspect of a software system such as structure, behavior, requirement,and so on. First you need to understand a diagram is not a model. Many users are confusing the difference between diagramming or drawing tools such as Microsoft Visio and modelingtools such StarUML or Rational Software Architect. Organizing Project See the Organizing Project section. If you want to know moreabout UML Elements, please refer to OMG UML Specification. Typically Project is organized as a set of UMLModels, UMLPackages, or UMLSubsystems. Modeling a software system requires describing multiple models because it is not enough to describe the system with asingle perspective, so we typically make multiple models such as Use-Case Model, Design Model, Component Model,Deployment Model, or others in a Project. Project is a top-level element stored as a single file. 354.10 Working with Communication Diagram. 254.4 Working with Composite Structure Diagram. 18Ĥ Modeling with UML 194.1 Organizing Project. 6ģ Editing Elements and Diagrams 73.1 Editing Diagrams.
