Conceptual Diagrams

A conceptual data diagram provides a graphical view of the conceptual structure of an information system, and helps you identify the principal entities to be represented, their attributes, and the relationships between them.

Note:

To create a conceptual diagram in an existing CDM, right-click the model in the Browser and select New > Conceptual Diagram. To create a new model, select File > New Model, choose Conceptual Data Model as the model type and Conceptual Diagram as the first diagram, and then click OK.

In the following conceptual diagram, the Teacher and Student entities inherit attributes from the Person parent entity. The two child entities are linked with a one-to-many relationship (a teacher has several students but each student has only one main teacher).
