  1. Package Diagrams • A package diagram is a UML diagram composed only of packages and the dependencies between them. A package is a UML construct that enables you to organize model elements, such as use cases or classes, into groups. Packages are depicted as file folders and can be applied on any UML diagram. Create a package diagram to: • Depict a high-level overview of your requirements (overviewing a collection of UML Use Case diagrams) • Depict a high-level overview of your architecture/design (overviewing a collection of UML Class diagrams). • To logically modularize a complex diagram.

  2. General Guidelines • Give Packages Simple, Descriptive Names •  Apply Packages to Simplify Diagrams • Packages Should be Cohesive • Indicate Architectural Layers With Stereotypes on Packages • Avoid Cyclic Dependencies Between Packages • Package Dependencies Should Reflect Internal Relationships
