The class diagram provides an analysis of the software system and displaying attributes, classes, their relationship, and operations.UML class diagram consists of operations, class name, and attributes in isolate designated compartments. Additional information about the relationship could be obtained by attaching the association relationship with the association class. 0000059035 00000 n 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.
