(b) functional dependencies F = H → D, B → AI, I → BC, DH → I, ABG → HI. Note that A, B, C, D, E,G, H, and I are attributes. Consider the relational schema R(A, B,C, D, E,G, H, I) and a set of i. Regarding F, is the decomposition R1 = ABCG, R2 = DEGHI of R lossless join? Please justify your answer.
