Hi all.
I'm in the beginning stages of learning relational database design (in Access) and am trying to understand the concept of referential intregrity.
I can see why this is important to insure the integrity of the data, so that foreign keys aren't left pointing to nowhere.
However, by default, Access has it turned off, whereas it seems like one would want to use it, more often than not.
Under what conditions would it be appropriate to having it turned off (i.e. no referential integrity)?
Any help would be appreciated.
