For relation R=(L, M, N, O, P), the following dependencies hold: M→O, NO→P, P→Land L→MN R is decomposed into R1 = (L, M, N, P) and R2 = (M, O).What is the highest normal form satisfied by the above decomposition? My doubt is For R1 it is in 2NF and R2 it is in BCNF .But ,dependency preserving also violates .So whts the highest normal form ?
