Question: Let R(A,B,C) be a relation schema, and let R 1 (A,B) and R 2 (A,C) be a decomposition of R. 1) Determine a set F

Let R(A,B,C) be a relation schema, and let R₁(A,B) and R₂(A,C) be a decomposition of R.

1) Determine a set F of non-trivial functional dependencies for R such that the decomposition of R in R₁ and R₂ is lossy and dependency-perserving. Explain why your selection of F is dependency-perserving.

2) Explain why your selection of F in the previous question is not a lossless decomposition.
