  • It can also be used to define the groupings amongst packages and other packages or objects.
  • It can complex structure in technology, education, and other related fields into simplified packages.

Basic Components of Package Diagram

  • Package – this is a namespace used to group related elements within a system.
  • Packageable Element – it can be rendered as a rectangle that can be labeled with a suitable name. This includes events, components, use cases, and packages.
  • Dependencies – This is a representation of how elements influence another.
  • Element Import – This is used to import individual elements without resorting to a package import.
