This Online Package Diagram Software pattern is used to group elements and define their interdependencies (packages). Package diagrams' primary goal is to simplify complex class diagrams that can group classes into packages. These groups aid in the definition of the hierarchy. It is worth noting that the package's UML elements are based on logical relationships. A package diagram is a collection of defined elements that are semantically linked and can be changed in tandem. It is the arrangement of model elements and the definition of their relationships.
