Define Component In Ooad

A component in the Unified Modeling Language represents a modular part of a system that encapsulates the state and behavior of a number of classifiers. In programming and engineering disciplines a component is an identifiable part of a larger program or construction.

It can be uniquely identified by its name and it defines a state which is represented by the values of its attributes at a particular time.

Define component in ooad. UML Component diagrams are used in modeling the physical aspects of object-oriented systems that are used for visualizing specifying and documenting component-based systems and also for constructing executable systems through forward and reverse engineering. Systems are constructed by interconnecting components Boundaries EnvironmentsCharacters Emergent Properties which may well be systems in their own right. Complexity Chapter 1 ComplexitySystems.

In Unified Modeling Language a component diagram depicts how components are wired together to form larger components or software systems. This is applied throughout the development life cycle of the application or system fostering better product quality and even. Provided services to other components requested services from other components An interface is a collection of 1 methods and 0 attributes Interfaces can consist of synchronous and or asynchronous operations A port square is an.

Its behavior is defined in terms of provided and required interfaces is self-contained and substitutable. A program consisting of four objects. 30 Component Diagram UML20 architectural view ComponentComponent Explicit description of interfaces.

They are used to illustrate the structure of arbitrarily complex systems. A class may be manifested by one or more components and in turn an component may be deployed on one or more nodes. Component diagrams are essentially class diagrams that focus on a systems components that often used to model the static.

An object is an instance of a class. An object is an entity that has state behavior and identity. Object Oriented System Analysis and Design Chapter 1.

Usually a component provides a particular function or group of related functions. Object-oriented analysis and design OOAD is a technical approach used in the analysis and design of an application or system through the application of the object-oriented paradigm and concepts including visual modeling. In this approach component diagrams allow the planner to identify the different components so the whole system does what its supposed to do.

A number of UML standard stereotypes exist that apply to components. In programming design a system is divided into. More commonly in an OO programming approach the component diagram allows a senior developer to group classes together based on common purpose so that the developer and others can look at a software development project at a high level.

Component is the manifestation of a set of logical elements such as classes and collaborations and a node is the location upon which components are deployed.
