Can transitive relations in 3NF cause redundancies amongst other problems?

Question

I know that redundancies can cause the user to inadvertently delete certain information, but that only applied, I believe, for 2NF. What about 3NF? I know there are transitive relations in 3NF too; however it is reciprocal between two determinants, so I believe the problem must be of a different nature. Also, is there any other issues with 3NF?

Answer 1

If you're compliant to 3NF, you'll be covered for the vast majority of cases. Coming across one of the special cases covered under Boyce-Codd, 4NF or 5NF is quite rare
