Explore Templates and Usecases Enterprise grade capabilities that are super simple to use Class diagrams are the only diagrams which can be directly mapped with object-oriented languages and thus widely used at the time of construction.UML diagrams like activity diagram, sequence diagram can only give the sequence flow of the application, however class diagram is a bit different. We are not interested in how the objects interact or change each other, but rather we want to represent how objects and actors act along a linear time axis. It shows the classes in a system, attributes, and operations of each class and the relationship between each class.
