What is an entity relationship diagram called up with sample data?

Question

Sometimes it happens a lot that the basic diagram of the relationship of objects does not reflect. I have seen and often make charts that contain several rows of data for each table, because it tells you more about relationships and design.

Is there a name for these types of charts? I am tempted to call this the “use case” of a data model.

Answer 1

I did not see an ERD diagram with several rows of samples for each table, but I saw diagrams that are designed to display examples of objects with specific attribute values ​​and their relationships with other objects. These are called instance diagrams .

This would be very similar to what you are asking for, except that I would not say that they show "several" lines, but one line of the "main" object and, possibly, more than one of the related child objects.
