7M822 What is the UML? The Unified Modelling Language (UML) is the successor to the wave of object-oriented analysis and design (OOA&D) methods that appeared in the late ’80s and early ’90s. It unifies the methods of Booch, Rumbaugh (OMT), and Jacobson (3 amigo’s).

7M822 Data and Processes Traditional, the division between data and processes –were structured separately, –and functions made use of data For OO –an object contains data and processes encapsulation information hiding –avoiding domino effect adaptations –more simple and cheaper maintenance

7M822 UML is for visualizing An explicit model facilitates communication. UML symbols are based on well-defined semantics.

7M822 UML is for specifying and constructing Specifying means building models that are precise, unambiguous and complete. UML addresses the specification of all the important analysis, design, and implementation decisions made in developing and deploying a software system. UML models are related to OO programming languages.

7M822 UML is for documenting UML addresses the documentation of a systems architecture and all of its details.

7M822 UML is a language UML is a visual language for software blueprints –with a vocabulary and rules for communication; –and a focus on conceptual and physical representations.

7M822 UML Models, Views and Diagrams A diagram is a view into a model –presented from the aspect of a particular stakeholder –and provides a partial representation of the system

7M822 UML Views Logical view Concurrency view Component view Deployment view Use Case view

7M822 UML Diagrams Structure diagram –Class diagram –Object diagram –Component diagram –Deployment diagram –Package diagram Behaviour diagram –Use Case diagram –Activity diagram –Interaction diagram Sequence diagram Collaboration diagram
