lossless-join decomposition

  1. Prove that the 3NF synthesis algorithm produces a lossless-join decomposition of the relation containing all the original attributes.
  2. Prove that an MVD X →→ Y over a relation R can be expressed as the join dependency ? {XY; X(R − Y )}
  3. Prove that if R has only one key, it is in BCNF if and only if it is in 3NF.
  4. Prove that if R is in 3NF and every key is simple, then R is in BCNF.
