What is UML? Unified Modeling Language (UML) Supports modeling, analysis and design of object-oriented software systems Includes several views Each view describes a system from a different perspective Each view is supported by one or more diagrams Maintained by Object Management Group (OMG) Visit www.omg.org more information

Modeling and Abstraction Purpose of a model is to study some properties of the entity being modeled Abstraction provides mechanism to concentrate on specific aspects of a system ignoring internal details Together, abstract models enable designers to study the properties of a system ignoring internal details UML provides the syntax, semantics and pragmatics to develop models at various levels of abstraction

Views in UML

Views supported by UML Use Case view Describes high level functionalities of the system Used by stakeholders, designers, developers and testers Described by use case diagrams The first view expected to be developed using the unified modeling process; it serves as the basis for other views

Views supported by UML (continued) Logical view Describes functionalities to be designed and to be implemented Describes static and dynamic aspects of the system Used by mostly designers and developers Described by class diagrams, object diagrams, state diagrams, interaction and activity diagrams (dynamic view)

Views supported by UML (continued) Process view Describes various processes in the system Mostly used by developers and testers Described by state diagrams, interaction and activity diagrams Supports concurrency and handling of asynchronous events

Views supported by UML (continued) Deployment view Describes physical architecture and assignment of components to architectural elements Mostly used by designers, developers and managers Described by package, component and deployment diagrams
