The document discusses Unified Modeling Language (UML) and enterprise architecture (EA). UML is a visual language for modeling software systems using diagrams, allowing developers and others to understand systems. UML diagrams are created based on object-oriented analysis and design of a system. EA frameworks help organize a business's operations and structure to achieve goals. EA ensures information technology supports all business functions. Common EA frameworks include the Zachman Framework and Federal EA Framework. Developing an effective EA program requires investment but helps prevent business disintegration.
