Database Modeling

Good morning!

I have the following problem in user, form, and group relationships. In the way that the relationship was modeled (CONTEM) it will become a table where you will have the user, form and group keys.WHAT IF YOU DO NOT HAVE THE FORM REGISTERED IN THE SYSTEM (HAVING PENALTY USER AND GROUP KEYS), WHAT DO I IN THE TABLE (CONTAINS) WITH RELATION TO FK THAT WOULD COME FROM FORM? WHERE THE FORM KEY GOES AS A FOREIGN KEY TO THE TABLE (CONTINUE) SINCE THE RELATIONSHIP IS FROM N N N.

But you can not set the Form Id to default null? Once the form is created, you make the link.

I think if it really is an FK, it should be defined in the bank schema for performance issues and guarantee the bank's relational model. But I see no reason not to set it to null.

Create only the relational table and do not set the foreign key fields, you can store the values even if you have only one value.
