In this video we have covered and understood SQL database normalization step by step with real practical examples where we did SQL table design mistake and rectified by applying normal forms that is 1st Normal Form(1NF) 2nd Normal Form(2NF), 3rd Normal Form(3NF), Boyce Codd normal form(BCNF) and 4th Normal Form(4NF).
So this database normalization in sql is not just fundamental video but a real time practical example video where we have shown how a database developer create SQL table design mistake and due to that what scalability problems we get and at a same time how to fix those design mistake by applying SQL Database Normalization rules step by step.
Here we cover 1st Normal Form (1NF)
Primary Key
Atomic Value
No Repeating Group
No Redundant Columns
2nd Normal Form (2NF)
Satisfy 1st Normal Form (1NF)
Remove Partial Dependency
3rd Normal Form (3NF)
Satisfy 2nd Normal Form (2NF)
Remove Transitive Dependency
Boyce Codd normal form (BCNF)
Satisfy 3rd Normal Form (3NF)
Remove Functional Dependency of Non-prime attribute deriving prime attribute
4th Normal Form (4NF)
Satisfy BCNF and 3rd NF (3NF)
Remove Multi-Valued Dependency
