This document outlines 50 differences between various Unified Modeling Language (UML) diagrams, including differences between class diagrams and other diagrams like sequence diagrams, activity diagrams, use case diagrams, and component diagrams. It also provides differences between diagrams like sequence diagrams and collaboration diagrams, activity diagrams and workflow diagrams, and statechart diagrams and state-transition diagrams. For more updated differences, the document recommends visiting a blog dedicated to differences between questions and answers.
