There are several other minimal bases for R.

Can you consider the rest???

Minimal Set of Functional Dependencies - Example Consider a relation R(A, B, C) such that each attribute functionally determines the other two attributes. The full set of derived FD's thus includes six FD's with one attribute on the left and one on the right A-> B,A c, B A,B C,C-, A, and C-9 B. with one attribute on the left and one on the right It also includes the three nontrivial FD's with two attributes on the left: AB C, AC B, and BCA. There are also FD's with more than one attribute on the right, such as A BC, and trivial FD's such as A-A. Relation R and its FD's have several minimal bases. One is A B, B-A, B C,C B). Another is (A B, B C, C->A). There are several other minimal bases for R. (can you discover the rest!)
