I have an UserDAO and an CountryDAO object.
When I insert an User object into database, first I must check if the Country for that user exists in database (if nobody deleted it).

If I check this in insertUser() method from UserDAO object, I must get a reference of CountryDAO object. This seems wrong to me, because I tight couple two DAO objects.

If I am doing this on a Service layer, using those 2 DAO objects as members in Service, It whould be esier to do this checking at this level, but is this business logic? Is not more Data integrity logic?
