Having identified potential objects and operations (or ‘methods’) during the creation of our sequence diagrams, we are now in a position to model the logical relationships between those objects using the UML Class Diagram. They illustrate how the different parts of a system interact with each other to carry out a function, and the order in which the interactions occur when a particular use case is executed. We go through various processes too, as do many natural phenomena. They capture the interaction between objects in the context of a collaboration.
