Database Administration Interview Question: Database Normalization

Can you explain the process of database normalization and why it's important?

Database normalization is the process of organizing a database efficiently, reducing redundancy, and ensuring data integrity. It involves breaking down a database into smaller, manageable tables and establishing relationships between them. This process helps in avoiding data anomalies and inconsistencies.

Database normalization is important because:

  • It minimizes data redundancy, which in turn reduces storage space and improves data consistency.
  • It simplifies database design, making it easier to manage and modify the database structure.
  • It improves query performance by eliminating redundant data and unnecessary join operations.
  • It ensures data integrity by enforcing data consistency and reducing the likelihood of data anomalies.

Overall, database normalization is crucial for maintaining a well-structured and efficient database system.
