Suppose that R =(R; F) is a schema and that R 1 =(R 1 ; F 1 ), R 2 =(R 2 ; F 2) is a binary decomposition such that neither (R 1 ? R 2 ) ? R 1 nor (R 1 ? R 2) ? R 2 is implied by F. Construct a relation, r, such that r ? ? R1 (r) ? R 2 (r), where ? denotes strict subset. (This relation, therefore, shows that at least one of these FDs is necessary for the decomposition of R to be
