I am now developing a database having information about universities. The database has a feature to prevent a duplicate name for the university title. I actually wonder of whether it is possible for 2 universities/colleges to have the same name in one country or different countries.
EDIT: I am actually not asking to make this database field the unique identifier for my university entries, but rather for preventing potential duplicate of a university when the the data entry guys use the system. I know I can do a quick check on duplicates but I thought to use this Unique attribute if universities have unique names worldwide.
