What are the different database normalization techniques?
Database normalization is a process to organize data in a database. The main techniques include 1NF, 2NF, 3NF, BCNF, and 4NF.
Can you explain the first normal form (1NF)?
1NF requires that all columns in a table contain atomic values, meaning each value must be indivisible.
What about the second normal form (2NF)?
2NF builds on 1NF by ensuring that all non-key attributes are fully functionally dependent on the primary key.
Why is normalization important in databases?
Normalization reduces data redundancy and improves data integrity, making databases more efficient and easier to maintain.
