This UML Package Diagram can be used in various systems and projects. The most common application of package diagrams is to organize case diagrams and class diagrams. They are also used to manage the layered architecture of any large-scale software system visually. Package diagrams also show the import and access dependencies of various elements, such as packages, classes, and components. Because package diagrams are so versatile, we can use them to show structure and dependencies between subsystems or modules. These diagrams also include packages with use cases that demonstrate the functionality of a software system.
