Timing Diagram What is a Class Diagram? The class diagram is a central modeling technique that runs through nearly all object-oriented methods. This diagram describes the types of objects in the system and various kinds of static relationships which exist between them.
History of object-oriented methods and notation Before UML 1.
The timeline see image shows the highlights of the history of object-oriented modeling methods and notation. It is originally based on the notations of the Booch methodthe object-modeling technique OMT and object-oriented software engineering OOSEwhich it has integrated into a single language.
They were soon assisted in their efforts by Ivar Jacobsonthe creator of the object-oriented software engineering OOSE method, who joined them at Rational in During the same month the UML Partners formed a group, designed to define the exact meaning of language constructs, chaired by Cris Kobryn and administered by Ed Eykholt, to finalize the specification and integrate it with other standardization efforts.
The result of this work, UML 1. Recent researchers Feinerer,  Dullea et al. Hartmann  investigates this situation and shows how and why different transformations fail.
The Superstructure that defines the notation and semantics for diagrams and their model elements The Infrastructure that defines the core metamodel on which the Superstructure is based The Object Constraint Language OCL for defining rules for model elements The UML Diagram Interchange that defines how UML 2 diagram layouts are exchanged The current versions of these standards are : UML Superstructure version 2.
It continues to be updated and improved by the revision task force, who resolve any issues with the language. Modeling[ edit ] It is important to distinguish between the UML model and the set of diagrams of a system.
A diagram is a partial graphic representation of a system's model. The set of diagrams need not completely cover the model and deleting a diagram does not change the model.
The model may also contain documentation that drives the model elements and diagrams such as written use cases. UML diagrams represent two different views of a system model: It includes class diagrams and composite structure diagrams. Dynamic or behavioral view: This view includes sequence diagramsactivity diagrams and state machine diagrams.
Use cases are a way of specifying required usages of a system. Typically, they are used to capture the requirements of a system, that is, what a system is supposed to do.The Unified Modeling Language (UML) is a standard visual modeling language to document business processes and software architecture using several types of diagrams - use case diagrams, class, package, component, composite structure diagrams, deployments, activities, interactions and profiles.
The site provides graphical notation .
UML, short for Unified Modeling Language, is a standardized modeling language consisting of an integrated set of diagrams, developed to help system and software developers for specifying, visualizing, constructing, and documenting the artifacts of software systems, as well as for business modeling and other non-software systems.

Search Search. The Unified Modeling Language (UML) was created to forge a common, semantically and syntactically rich visual modeling language for the architecture, design, and implementation of complex software systems both structurally and behaviorally.
UML has applications beyond software development, such as process flow in manufacturing. The Unified Modeling Language (UML) is a general-purpose, developmental, modeling language in the field of software engineering, that is intended to provide a standard way to visualize the design of a system.
