What is natural join in relational algebra? - Database management system
Presidency University, Bangalore- Database management system
Natural Join (⋈):
Natural join does not use any comparison operator. It does not concatenate the way a Cartesian product does. We can perform a Natural Join only if there is at least one common attribute that exists between two relations. In addition, the attributes must have the same name and domain.
Natural join acts on those matching attributes where the values of attributes in both the relations are same.
