Now that we know formally what Boyce-Codd Normal Form represents for decomposed relations, we can expand on the basic example in the previous video with this more in-depth walk through. This video shows the step by step process of decomposing relations into BCNF. This video is part of a series on database normalization, and a larger course on Databases.
If you have not already seen our video on database anomalies decomposition and Boyce-Codd Normal Form please find it here: • 4.0 Database Normaliza...
We see how to use decomposition to break apart relations into ones that are free of these anomalies. This video ends by explaining what Boyce-Codd Normal Form (BCNF) is and shows a basic example of how to decompose relations to it.

Thank you so much! After countless hours of trying to figure out BCNF decomposition I figured it out after watching this video!

What happens if both the relations that we have splitted do not have the attributes the FD has, will we just ignore and lose that FD? Because we cannot determine in which table it should be in?
