Object Modelling Using Uml

Unified Modeling Language UML is a standardized visual modeling language that is a versatile, flexible, and user-friendly method for visualizing a system's design. Software system artifacts can be specified, visualized, built, and documented with the use of UML. We use UML diagrams to show the behavior and structure of a system.

UML is a combination of several object-oriented notations Object-Oriented Design, Object Modeling Technique, and Object-Oriented Software Engineering. UML uses the strengths of these three approaches to present a more consistent methodology that's easier to use.

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 reference and examples of all types of UML diagrams.

c Paul Fodor UML Diagrams UML - Unified Modeling Language UML diagrams are used to design object-oriented software systems represent systems visually Client-friendly! provides a system architecture makes coding more efficient and system more reliable diagrams show relationships among classes and objects Can software engineering be automated?

The purposes of object diagrams are similar to class diagrams. The difference is that a class diagram represents an abstract model consisting of classes and their relationships. However, an object diagram represents an instance at a particular moment, which is concrete in nature. It means the object diagram is closer to the actual system behavior.

In object oriented modeling, the main building block of all software systems is the object or class. Simply put, an object is a thing, generally drawn from the elements of the problem space or the solution space. A class is a description of a set of common objects. Every object has state, identity and behavior.
