Chapter 7 Linking and Synchronizing Models in PowerDesigner

Introduction

The PowerDesigner Enterprise Modeling environment permits you to create and exploit complex interdependencies between your models.

When you, for example, generate one model from another, or create a shortcut or define mappings from one model to another, you can track and analyze these dependencies via property sheets. You can also use impact analysis , to evaluate how changes made in one model may affect associated models.

The following types of interdependencies can be created between models:

Generation links - created during model generation. Each generated object is linked with its origin object.
Shortcuts - references that you create explicitly to objects in other models (target objects). When models are open in the workspace, you can see the links between shortcuts and other objects in the Dependencies tab of target objects.
Manual links. automatically created in several other cases: when you link objects using extended or calculated collections, extended dependencies, or related diagrams. When you create manual links, shortcuts are silently created in the model.
