Package: This is the fundamental unit of a package diagram, serving as a container for various elements like classes and interfaces. It’s depicted as a folder-like icon with a name label, making it easy to identify.
Pretty much all UML elements can be grouped into packages. Thus, classes, objects, use cases, components, nodes, node instances etc. can all be organized as packages, thus enabling a manageable organization of the myriad elements that a real-world UML model entails.
Package is a namespace used to group together elements that are semantically related and might change together. It is a general purpose mechanism to organize elements into groups to provide better structure for system model. Owned members of a package should all be packageable elements.
UMLpackage diagrams document the structure of grouped components in a system along with their dependencies, especially for multi-layered web and application architectures.
A package diagram in UML (Unified Modeling Language) is a structural diagram that groups related elements such as classes or components into logical units called packages. It shows how these packages are organized and depend on each other, offering a clear view of a system’s structure.
