UML I An industry standard modelling language for Structure Diagrams object-oriented software engineering. Behaviour Diagrams I Developed in the mid-1990's and standardised in 1997 Interaction Diagrams (UML 1.1). Modelling I UML 2.x is the current revision in use (we will focus on Use Case UML 2.0, revision from 2005). summary I UML includes a set of graphic notation techniques to create visual models of object-oriented software-intensive systems.

Introduction to Class Diagram UML Course Information Shows a collection of static model elements such as classes UML Structure and types, their contents, and their relationships. Diagrams Behaviour Diagrams Interaction Diagrams Modelling Use Case summary Introduction to Object Diagram UML Course Information Depicts objects and their relationships at a point in time, UML typically a special case of either a class diagram or a Structure Diagrams communication diagram. Behaviour Diagrams Interaction Diagrams Modelling Use Case summary Introduction to Component Diagram UML Depicts the components that compose an application, system, or enterprise. The components, their Course interrelationships, interactions, and their public interfaces are Information UML depicted. Structure Diagrams Behaviour Diagrams Interaction Diagrams Modelling Use Case summary Introduction to Composite Structure Diagram UML Course Information Depicts the internal structure of a classifier (such as a class, UML component, or use case), including the interaction points of Structure Diagrams the classifier to other parts of the system. Behaviour Diagrams Interaction Diagrams Modelling Use Case summary Introduction to Package Diagram UML Shows how model elements are organized into packages as Course well as the dependencies between packages. Information UML Structure Diagrams Behaviour Diagrams Interaction Diagrams Modelling Use Case summary Introduction to Deployment Diagram UML Shows the execution architecture of systems. This includes Course Information nodes, either hardware or software execution environments, UML as well as the middleware connecting them. Structure Diagrams Behaviour Diagrams Interaction Diagrams Modelling Use Case summary Introduction to Use Case Diagram UML Shows use cases, actors, and their interrelationships. Course Information UML Structure Diagrams Behaviour Diagrams Interaction Diagrams Modelling Use Case summary Introduction to Activity Diagram UML Depicts high-level business processes, including data flow, or Course to model the logic of complex logic within a system. Information UML Structure Diagrams Behaviour Diagrams Interaction Diagrams Modelling Use Case summary Introduction to State Machine Diagram UML Describes the states an object or interaction may be in, as well as the transitions between states. Formerly referred to Course as a state diagram, state chart diagram, or a state-transition Information UML diagram. Structure Diagrams Behaviour Diagrams Interaction Diagrams Modelling Use Case summary Introduction to Sequence Diagram UML Models the sequential logic, in effect the time ordering of Course messages between classifiers. Information UML Structure Diagrams Behaviour Diagrams Interaction Diagrams Modelling Use Case summary Introduction to Communication Diagram UML Shows instances of classes, their interrelationships, and the Course message flow between them. Communication diagrams Information UML typically focus on the structural organisation of objects that Structure send and receive messages. Formerly called a Collaboration Diagrams Behaviour Diagram. Diagrams Interaction Diagrams Modelling Use Case summary Introduction to Timing Diagram UML Course Information UML Structure Diagrams Behaviour Depicts the change in state or condition of a classifier Diagrams Interaction instance or role over time. Typically used to show the change Diagrams in state of an object over time in response to external events. Modelling Use Case summary Introduction to Interaction Overview Diagram UML A variant of an activity diagram which overviews the control flow within a system or business process. Each node/activity Course within the diagram can represent another interaction Information UML diagram. Structure Diagrams Behaviour Diagrams Interaction Diagrams Modelling Use Case summary Introduction to UML Course Information UML Structure Diagrams Behaviour Modelling Diagrams Interaction Diagrams Modelling Use Case summary Introduction to System development UML Course Information I System development is model building UML I Complexity of a large project Structure Diagrams I A large number of components Behaviour Diagrams I A large amount of team work Interaction Diagrams I Linguistic communication between teams or between team members is neither accurate nor reliable Modelling Use Case I Models are standard representations and they are accurate and reliable summary I Modelling is the process of developing a model I Various types of models for different purposes and stages in software development Introduction to Types of models UML I Various types of models Course I Requirement model describes Information I Users' requirements UML I Functionality Structure Diagrams I Analysis model gives Behaviour System specifications Diagrams I Interaction I A robust and changeable structure and structured Diagrams components Modelling Use Case I Design model presents summary I A refined structure to the current implementation environment I Implementation model documents I Details of how a design is implemented I Test model gives I Verification I Validation Introduction to Architecture UML Course Information I Architecture of a modelling language UML Structure I Model architecture is a set of modelling language, Diagrams Behaviour notation and modelling techniques. Diagrams I A modelling language contains: Interaction Diagrams I Syntax - how it looks Modelling I Semantics - what it means Use Case I Pragmatics - heuristics and rules of thumb for using it summary I UML I Unified Modelling Language
