Equi-join:-

The equi-join of two relations R and S over the common attribute B is the set of all pairs of tuples, the first from R and the second from S, such that the values of attribute B are equal. The equi-join can also be defined relative to several common attributes. How does the equi-join of R and S over all common attributes differ from the natural join of R and S?
