Subject Foreign Key
Author Nico Callewaert

I know this is not the right group to ask, but I posted this message twice
in the ib-support list, no one answered. Maybe it's a dummy question,
anyway, not everybody can be a "master", so if no one mind, I would like to
ask this here. Maybe someone can answer me privately ? I have a Customer
table, and normally I could define 6 foreign keys to that table : Country,
language, coin, payment conditions.... Those fields are referencing fields
in other tables. Should I define those 6 foreign keys ? Or could I have
a performance problem after that ??
Is foreign keys a good thing to use ?

Many thanks,

Nico Callewaert
