Chapter 3 Getting Started with the PowerDesigner Eclipse Plugin
A typical hierarchy of objects in a PowerDesigner Model Explorer tree is as follows:
Projects can contain user-defined folders, which allow you to organize models or other files into groups. For example, if you are working on two separate projects, you could organize the files using folders. For more information about folders, see the "Using the PowerDesigner Interface" chapter.
A model is the basic design unit in PowerDesigner. Each model has one or more graphical views called diagrams and any number of model objects.
When you are working with large models, you may want to split them into smaller "sub-models" in order to avoid manipulating large sets of items. These sub-models are called packages, and can be used to assign different tasks or subject areas to different development teams. For more information, see the section "Working with Packages".
Diagrams show the interaction of various model objects. You can create several diagrams in a model or in a package.
Model objects is a general term used for all items belonging to a model. Some model objects, such as a class in an Object-Oriented Model, have graphical symbols while others, such as business rules, do not appear in diagrams and can only be accessed from the Model Explorer or from an object list. For more information, see the section "Working with Objects".
You can document your PowerDesigner models by creating automatically-generated single or multi-model reports in the Report Editor.
