The document introduces Unified Modeling Language (UML) by describing its history, elements, and common diagram types. It explains that UML was created to model systems using object-oriented concepts and visualize software structure. The key elements are things, relationships, and diagrams. Common diagram types include use case diagrams, class diagrams, sequence diagrams, and deployment diagrams.
