Back end data Relationships

When an access application has front and back should relationships be created in the data end or the front end and does one override the other?

I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

yes, relationships are created in the back and backend overrides whatever is designed in app

that's because You define relationships as FK to PK and in this case it will enforce /override whatever You define on the front end

say you have pk to fk emp to dept relationship , You try build a form to enter info for new employee ,You'll have to supply department details as it's FK defined in emp table that will enforce the rule, so You have to build Your form the right way, displaying department info / search department number by other info if needed.

Relationships are only honored within the DB container where the table physically resides.  Relationships cannot span DB's

Defining relationships in the FE does nothing other then provide join hints for the query designer.
