R(A,B,C,D,E) {A $\rightarrow$ B , AB $\rightarrow$ C, D $\rightarrow$ AC, D $\rightarrow$ E}
R1(A,C,D){ D $\rightarrow$ AC , A $\rightarrow$ C }
R2(D,E) {D $\rightarrow$ E}
R3(A,B,C) { A $\rightarrow$ B, AB $\rightarrow$ C}
All dependency preserved .
R1 And R2 can combine i.e. R1R2( A,C,D, E) and then combine R1R2 and R3(A,B,C) where common attributes(AC) is a key of R3.. so lossless decomposition.
