A component diagram has a higher level of abstraction than a Class Diagram - usually a component is implemented by one or more classes (or objects) at runtime. Let us elaborate this by reviewing the classes in the Courseware Management System. In the diagram below, each component is enclosed in a small box. Edraw Diagram Component is a diagramming tool which can be used to create different kind of diagrams and can be integrated to other applications as an activeX control. In the next article, we will cover the last UML diagram—the Deployment diagram. In a component diagram, components are generic types rather than instances. A provided interface is modeled using the lollipop notation and a required interface is modeled using the socket notation. When modeling large object-oriented systems, it is necessary to break down the system into manageable subsystems. The diagram also depicts a database access component that represents a library component that the Model layer components will use to interact with a database. The following deployment diagram shows the relationships among software and hardware components involved in real estate transactions. In this article, we briefly discussed Component diagrams. Dependencies indicate that a client component is dependent upon a supplier component in some way. Each package represents a subsystem and groups a set of cohesive responsibilities of classes. A component diagram is similar to a class diagram in that it illustrates how items in a given system relate to each other, but component diagrams show more complex and varied connections that most class diagrams can. In my previous article on the UML’s class diagram, I described how the class diagram’s notation set is the basis for all UML 2’s structure diagrams.Continuing down the track of UML 2 structure diagrams, this article introduces the component diagram.

This partitioning of the different classes of the application poses its own challenges, the primary one being how do the classes in one layer interact with the classes in the other layers. By Moaaz Ahmad. In UML 2, a component is drawn as a rectangle with optional compartments stacked vertically. Components also require interfaces to carry out a function. Subscribe to our newsletter below. An added advantage of basing your application components on these component models is that your components become "reusable!". Figure 2 shows the Component diagram for the Model layer of the Courseware Management System. But, to enable our application components to be used by external applications, we can consider basing the components on well-defined component standards. A component represents a modular part of a system that encapsulates its contents and whose manifestation is replaceable within its environment. Basic Concepts of Component Diagram. This example shows the basic components of a store. Before we move to identifying the components, let us recap a quick discussion that we had regarding the Model View Controller architecture in the UML Class Diagram Part II article. In UML, Components are made up of software objects that have been classified to serve a similar purpose. NOV Diagram for .NET.

In the context of the Unified Modeling Language (UML), a deployment diagram falls under the structural diagramming family because it describes an aspect of the system itself. Updated: 2 years ago. The diagram also depicts a database access component that represents a library component that the Model layer components will use to interact with a database. To show component instances, use a deployment diagram. These components are libraries, packages, files, etc.Component diagrams ca… The purpose is also different from all other diagrams discussed so far. Create Component Diagram examples like this template called Component Diagram - Web Application that you can easily edit and customize in minutes. A high-level, abstracted view of a component in UML 2 can be modeled as: Deployment Diagram Examples. As an example, a Component diagram for the Web Application of a simplified, fictional Internet Banking System might look something like this. For example, the Ruby on Rails web development framework is available with the MIT licence, which means it can be modified, upgraded, and used without any restrictions. In the first instance, the application may seem to be too simplistic to contain components. We can as well define our own set of simple interface methods to access these services. In TE000130250: Under Template Categories, click Software, and then click UML Model Diagram, and then click Create. The main purpose of a component diagram is to show the structural relationships between the components of a system. By classifying a group of classes as a component the entire system becomes more modular as components may be interchanged and reused. Namely, the two structural web app components any web app consists of – client and serversides. An interface is the definition of a collection of one or more methods, and zero or more attributes, ideally one that defines a cohesive set of behaviors. The component diagrams represent implementation of view models. Hence, based on the technology that you use, you would model these as, maybe Enterprise JavaBeans (EJBs) or Component Object Model/Distributed Component Object Model (COM/DCOM) components. Based on this, let us now draw the components in the Model layer for the Courseware Management System. Before we start, let’s make sure we’re on the same page regarding the key technical web-related terms. [Server (computing). 4.0625 (16) Component Diagram for Online Shopping System.
