Saving a Model

When a model contains unsaved changes, an asterisk is appended to its name in the Browser.

When you save a model or a multi-model report, PowerDesigner automatically assigns to the file a unique identifying number called GUID (Global Unique ID), and creates a backup copy of your file with the same identifying number. The GUID is used:

In the Repository, to allow documents to be identified and updated
During model generation

The following formats are available when you save a model:

Format	Description
XML	[default] The saving and loading time is longer (1.5x) than binary, and the file size is bigger (2.5x) than binary. You can open and modify the contents of an XML model file. XML is recommended for small models.
Binary	Saving and loading time is shorter than XML, and the file size is smaller than XML Recommended for big models.

Saving a Model as a New File with the Same GUID
You can create a backup version of a model with the same GUID as the original.
Saving a Model as a New File with a New GUID
You can save the model as a new model with a new GUID. This allows you to develop two separate models in parallel, starting from the same set of model objects.
