In the MERISE methodology, the conceptual data model defines the objects and the actions that must be taken into account in the database.

To associate a CDM (Conceptual Data Model) with a project, you must generate the associated LDM (Logical Data Model).

The data model editor allows you to easily create entities in a CDM (Conceptual Data Model).

In conclusion, a semantic model is far more than a conceptual data model (it contains the CDM and we can, at any moment, extract the data model from a semantic model.

2nd method: Create the Conceptual Data Model (CDM), then automatically create the analysis from the CDM.
