Answer from AI
Normalizing database data structures is important for:
- Eliminating data redundancy, which reduces storage space and prevents duplication.
- Ensuring data integrity, as changes in one place are automatically reflected in related tables.
- Simplifying database maintenance and updates.
- Improving query quality and preventing anomalies during data insertion, updating, or deletion.
Advantages of normalization:
- More efficient use of disk space.
- Increased reliability and consistency of data.
- Simplified application logic due to a clear data structure.
For example, instead of storing information about clients and their orders in one table, data is divided into "Clients" and "Orders" tables, linked by a key. This prevents repetition of client information in each order.
