![]() They enable you to design your classes, which become the building blocks of your application.Ĭlass diagrams allow you to document the structure (attributes and operations) of classes. Class diagrams can help immensely in this regard. This requires that you create families of classes (most importantly business object classes) that have crisp boundaries and a balanced distribution of responsibilities. If you're creating monolithic applications where the application and data access logic is melded together inside the user interface, you will find little use for class diagrams?or the entire UML for that matter! Fortunately, many software developers are beginning to understand the importance of creating component-based applications that can be easily maintained, extended and scaled from the desktop to the Internet. For the most up-to-date information, check out the latest official version of the UML specification at Why Use Class Diagrams? It is not intended to be a completely comprehensive guide to class diagrams?that would require a book and, in fact, it's highly recommended that you refer to The Unified Modeling Language User Guide by Booch, Rumbaugh and Jacobson (Addison-Wesley) for the complete details on class diagrams. This article provides a practical overview of the most commonly used features of class diagrams. When used in conjunction with UML sequence diagrams (covered in the next article in this series), they can help you produce well-designed families of classes that form the foundation of flexible and extensible software applications. Class diagrams are most often used in the elaboration and construction phase of software projects. In this second article in the series, we take a close look at UML class diagrams. This article will cover the basics of class diagrams and help you see how you can use them in your software development?especially in building your business object classes. They are critical for helping you design classes that will serve as building blocks for your application. Class diagrams are among the centerpieces of the Unified Modeling Language.
