What is the Difference Between 3NF and BCNF - Pediaa.Com

Jan 21,2019 DBMS Normalization1NF 2NF 3NF and BCNF with#0183;The main difference between 3NF and BCNF is that the table should be in 2 nd normal form and there shouldnt be any transitive dependencies to satisfy 3NF while the prime attributes of the table should not depend on the non-prime attributes of the table to satisfy BCNF..Data redundancy refers to the same data repeating in multiple places.It can also cause issues in data insertion,update What is the Difference Between 3NF and BCNF - Pediaa.ComJan 21,2019 DBMS Normalization1NF 2NF 3NF and BCNF with#0183;The main difference between 3NF and BCNF is that the table should be in 2 nd normal form and there shouldnt be any transitive dependencies to satisfy 3NF while the prime attributes of the table should not depend on the non-prime attributes of the table to satisfy BCNF..Data redundancy refers to the same data repeating in multiple places.It can also cause issues in data insertion,update What is Normalization? Explain 1NF,2NF,3NF and BCNF Boyce-Codd Normal Form (BCNF) BCNF is an extension of Third Normal Form in strict way.A relationship is said to be in BCNF if it is already in 3NF and for any non-trivial functional dependency,X - DBMS Normalization1NF 2NF 3NF and BCNF withgt; A,then X must be a super-key.A 3NF table which does not have multiple overlapping candidate keys is said to be in BCNF.Example:
