Package diagram

A package diagram (English package diagram ) is one of the 14 chart types in the Unified Modeling Language ( UML), a modeling language for software and other systems.

The package diagram is a structural diagram. It shows a particular view of the structure of the modeled system. The presentation typically includes doing packages, package mergers, package imports and dependency relationships.

There are numerous applications for the package diagram. The metamodel of the UML2 itself is divided into packets and the specification of UML 2.0 Superstructure contains for each speech unit, a package diagram with which the organization is represented in sub-packages. In the modeling of software systems package diagrams are also used frequently. Package diagrams show there, for example, the layering of the software, or the division of the software into modules dar. In business models, packets are often used to summarize technically belong together parts of the model, for example, to business cases. A package diagram then displays a summary of transactions.

Examples
