Normalization is defined as what in database design?

• A. The process of applying rules to ensure data is divided into appropriate tables.
• B. The process of standardizing social norms within a community.
• C. The process of removing duplicates in memory.
• D. The process of archiving old records.

Answer: (A)

Normalization in database design is the process of organizing data by applying rules that ensure data is divided into appropriate tables to reduce redundancy and maintain data integrity. By breaking data into related tables and defining clear relationships and keys, each fact is stored in one place, which helps prevent update, delete, or insert anomalies and makes maintenance and queries more reliable. This aligns with the idea of applying formal rules to structure data rather than simply standardizing social norms, removing duplicates in memory, or archiving old records, which are different concepts not about how data is organized within a database schema.
