We've updated our video! • Learn how to make classes, attributes, and methods in this UML Class Diagram tutorial. There's also in-depth training and examples on inheritance, aggregation, and composition relationships. • UML (or Unified Modeling Language) is a software engineering language that was developed to create a standard way of visualizing the design of a system. And UML Class Diagrams describe the structure of a system by showing the system’s classes and how they relate to one another. • This tutorial explains several characteristics of class diagrams. Within a class, there are attributes, methods, visibility, and data types. All of these components help identify a class and explain what it does. • There are also several different types of relationships that exist within UML Class Diagrams. Inheritance is when a child class (or subclass) takes on all the attributes and methods of the parent class (or superclass). Association is a very basic relationship where there's no dependency. Aggregation is a relationship where the part can exist outside the whole. And finally, Composition is when a part cannot exist outside the whole. A class would be destroyed if the class it's related to is destroyed. • Further UML Class Diagram information: https://www.lucidchart.com/pages/uml-... • —— • 00:00 Introduction • 00:20 Class • 01:08 Attributes • 02:06 Methods • 03:05 Visibility • 4:04 Zoo system example • 4:29 Lucidchart • 04:59 Inheritance • 06:22 Abstraction • 06:55 Association • 07:15 Aggregation • 08:00 Composition • 08:46 Multiplicity • 09:37 Real-world example • 12:06 Conclusion • —— • Learn more: https://training.lucid.co • Sign up: https://www.lucidchart.com • Follow us: • Facebook: / lucidchart • Twitter: / lucidchart • Instagram: / lucidchart • LinkedIn: / luci. .
