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.

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.
