Class diagrams

Overview

The class diagram is a fundamental tool in object-oriented modeling. It's used for both high-level conceptual modeling of an application's structure and detailed modeling that translates into programming code. Class diagrams can also be applied to data modeling. In these diagrams, classes represent key elements, interactions within the application, and the classes to be programmed.
