All your models, diagrams, and model objects are stored and organized in the Browser.
Workspaces
A workspace contains all the information you need to perform a modeling task with PowerDesigner. It allows you to save your modeling environment in a file with a hierarchy of folders and models. During a work session, every change in the folder or models hierarchy is saved locally in the workspace.
Folders
A folder is a container object that can help you organize the hierarchy within your workspace. It can contain models, multi-model reports, and other folders. Folders are saved in the workspace file.
Model Files
You can create a new empty model by clicking the New tool, or populate a new model with existing data in one of the following ways:
Packages
A package is a piece of a model. When working with large models, you can split them into smaller subdivisions in order to avoid manipulating the entire model at once. Packages can be used to organize your model into different tasks and subject areas, and to assign parts of it to different development teams.
