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.
You can create several workspace files on your machine, but you can only work in one workspace at a time. Workspaces are saved in files with an .sws extension. They do not have property sheets
You can create the following new items in a workspace by right-clicking the workspace in the Browser and select New→item:
In addition, you can add existing items (including external files, such as text files or MS Word files, and other PowerDesigner workspaces) to a workspace by right-clicking the workspace in the Browser, selecting Add, browsing to the item, and clicking OK. When you have external files referenced in a workspace, you can open with a double-click.
A PowerDesigner model is the basic work unit, and may contain multiple packages and diagrams. You can use folders in your workspace to organize your models.
You can have a convenient environment for working with multiple interconnected models and other files by creating a project. For information, see Projects and Framework Matrices.
To modify the filename of closed models, multi-model reports, or any document type (workspaces or external files) you can right-click the item in the Browser and selecting Properties, the Document Properties dialog box allows you to directly modify the item filename.
It is highly recommended to keep original models and their corresponding generated models in the same workspace.
