Core Data foreign key/relationship between two tables

hi,

this is a very simple concept that I can't seem to solve using relationships with core data between two tables. for instance, I have a client table with a name field that I want to link to a client details table with a clientName field and when I update/edit the client name, this still stays links to the client details record. make sense?

I tried relationships but it does not link up when I edit the client name. I feel like I'm missing something very obvious here and have tried multiple scenarios but I'm not finding a solution nor am I finding any documentation on how this should work.

any help/ideas is appreciated.

Thank you,

Pete
