in this, you can see the concept of BCNF or Boyce-Codd Normal Form. Boyce-Codd Normal Form Potential problem with 3NF <ex> R=(Course#, Section #, Professor) F={C# S# Prof, Prof C#}, Key=(C# S#, Prof S#)-R is in 3NF although Prof S To ask your doubts on this topic and much more, click on this Direct Link: www.techtud.com/video-lecture/lecture-boyce-codd-normal-form-bcnf 3NF is the Third normal form used in relational database normalization. According to the Codd's definition, a table is said to be in 3NF, if and only if, that table Boyce-Codd Normal Form Edit. Boyce Codd normal for is used in Database Normalization. It is more strongly normalized than third normal form and less restrictive than Boyce-Codd Normal Form (BCNF) was introduced in 1974 by Codd and Raymond F. Boyce. What is 3NF? What is the difference between 3NF and BCNF? Difference between 3NF and BCNF in simple terms An example of the difference can currently be found at "3NF table not meeting BCNF (Boyce-Codd normal form) Boyce-Codd Normal Form - This normal form is also referred as 3.5 normal form. This normal form meets all the requirement of 3NF along with aditional criteria. To eliminate these anomalies in 3NF relations, it is necessary to carry out the normalization process to the next higher step, the Boyce-Codd Normal Form. What is the difference between BCNF and 4NF (Fourth Normal Form)? • Database must be already achieved to 3NF to take it to BCNF, but database must be in
