Why is normalization needed?

Normalization is the process of organizing data in a database to eliminate redundancy and ensure data integrity.

Main reasons for normalization:

• Elimination of data duplication: reduces the size of the database and lowers the risk of inconsistency.
• Ensuring integrity: data is stored in logically related tables with proper relationships.
• Simplifying maintenance and updates: changes in one place do not require multiple corrections.

For example, instead of storing information about clients and their orders in one table with repeating client data, normalization separates data into "Clients" and "Orders" tables, linking them through keys. This simplifies data management and increases efficiency.

In Go, normalization is important when designing database schemas, especially if a relational DBMS is used, to ensure scalability and reliability of the application.
