CDC - Circular connection?

I am new to coding and designing programs, and I truely apologize if this is a stupid question.

I have just auto-generated a CDC (Class design diagram) in Visual Paradigm of a fully working database handling program.

I don’t understand the “circular” connection around my CreateMember class and can’t seem to find the answer - probably because it is so obvious!

And, is “circular connection” even the right term? I have a slight feeling that it is not!


Would you please attach a screenshot about the “circular connection” you meaning? Thanks!

Best regards,
Rain Wong
