Normalization is the process of eliminating redundancy in a database by organizing the data into several smaller tables. The large tables are normalized (converted) into smaller tables by using normalization rules, so that a database administrator can ea…
Question
100%

Given the reation R (A, B, C, D , E), with functional dependencies:

  • A, B -> C
  • D, E -> C
  • B -> D

Could you explain why this is not functional dependency preserving? Also could you work out the BCNF for this?
