Part 1: What is The UML Class Diagram?

UML class diagram, a type of static structure diagram, is composed of classes, interfaces, associations, collaborations and constraints. Generally, the UML class diagram is used for visualizing, describing and documenting various aspects of an application but also for constructing executable code of the software application.

Unified Modelling Language (UML) is a type of language used to illustrate the inner workings of a system, which include its actors, actions, roles, and classes. Originally used in the fields of software and engineering, UML has now made its way into business, and is a popular method of documenting business processes.

The Usage of UML Class Diagram

UML primarily uses diagrams to represent systems. These diagrams can be broken down into two types: behavioural UML diagrams, and structural UML diagrams.

UML is an extremely versatile and widely-recognised language. It is the standard language used by many developers, as well as an increasing number of business professionals. Its flexibility means that it can be applied to a number of IT or business-related situations, so that you can make it applicable to the system or technology you are using.

Part 4: UML Class Diagram Examples

Following are a few UML class diagram examples that would help you understand the diagram versatility.

UML Class Diagram Example


Abstract factory design involves producing families of objects without specifying their concrete classes. This UML class diagram illustrates this process.

After the client software has created a concrete implementation of the abstract factory, it will then use the generic interfaces to create concrete objects that belong to the group of objects. As the client uses generic interfaces of their products, it does not take into account which concrete objects it gets from each of these concrete factories.

UML Class Diagram Example


This UML class diagram shows a library domain model. It is used to illustrate how the various classes connect and relate with each other in the Library Management System. Each physical library item is itemized and even barcoded, from books to cassette tapes. The benefit of barcoding is that each item is unique and identifiable once scanned.
