UML (Unified Modeling Language) is a standard language for modeling software systems using mainly graphical diagrams. It includes diagrams for use cases, class structure, object interaction, state machines, activities, components and deployment. UML aims to provide a standard way to visualize a system's architectural design which can be understood by all stakeholders and serves as input for the implementation.

17. Diagrams in UML A Diagram is the graphical presentation of a set of elements, most often rendered as a connected graph of things and relationships. UML includes 9 such diagrams. 1. Class Diagram. 2. Object Diagram. 3. Use Case Diagram. 4. Sequence Diagram. 5. Collaboration Diagram. 6. State Chart Diagram. 7. Activity Diagram. 9. Deployment Diagram.

34. Component Diagrams Component diagrams describe the organization of and dependencies among software implementation components. These diagrams contain components, which represent distributable physical units, including source code, object code, and executable code.

35. Deployment Diagrams Deployment diagrams describe the configuration of processing resource elements and the mapping of software implementation components onto them. These diagrams contain components and nodes, which represent processing or computational resources, including computers, printers, etc.
