A CDM file is a data model created by SAP PowerDesigner, an enterprise modeling and design program. It stores a diagram that may include data items, entities, relationships, association links, notes, and shapes. CDM files also store metadata, such as the creator, creation date, and modification dates of the model.

CDM files are created to store a saved conceptual data model, which allows you to analyze the conceptual structure of an information system in PowerDesigner. It is a more abstract version of a Logical Data Model (LDM file) or Physical Data Model (.PDM file).

To create a CDM file in Power Designer, select File → New Model, select the "Information" category, choose the "Conceptual Data" category item, click OK, then choose File → Save.

To open a CDM file in Power Designer, select File → Open and choose the Conceptual Data Model CDM file you would like to open.

NOTE: PowerDesigner was originally developed by Sybase, which was purchased by SAP.
