They show the different elements of a system and the relationships between them. The main structural diagrams are:  Class Diagram – Shows classes, attributes, methods, and relationships.  Object Diagram – Shows objects and their relationships.  Component Diagram – Shows software components and their dependencies.  Deployment Diagram – Shows the physical deployment of software on hardware....
