Defining packages

Defining packages

A package is a general purpose mechanism for organizing elements into groups.

When you are working with large models, you can split any model into smaller subdivisions in order to avoid manipulating the entire set of data of the model. Packages can be useful to assign portions of a model, representing different tasks and subject areas, to different development teams.

You can create as many packages as you need in a model. The name of each package must be unique in the model.

Package hierarchy You can create several packages at the same hierarchical level within a model. or decompose a package into other packages and continue this process without limitation in decomposition depth. At each level of decomposition you can create several diagrams.

Packages work as models, they can contain the following items:

Model objects

Other packages

Diagrams, in order to have different views of the contents of the package. Each package appears with a default diagram window

For more information on packages, see the PowerDesigner Feature Guide.

Package properties
