What is the objective of data normalization?

• A. To speed up data retrieval
• B. To enhance database security
• C. To minimize duplication of information
• D. To create a user-friendly interface

Answer: (C)

The objective of data normalization is primarily to minimize duplication of information. This process involves organizing the columns and tables of a database so that relationships among the data are properly defined. By eliminating redundant data, normalization helps in reducing the chances of inconsistent data entries, which can lead to errors and inaccuracies. Normalizing data can also lead to improved data integrity, as updates, inserts, and deletes become much more manageable when the database follows a structured form. While it can indirectly affect retrieval speed and database security, the main focus is on ensuring that data is stored efficiently and consistently without unnecessary duplication. In short, the purpose of normalization centers around achieving an optimally structured database, thus supporting accurate data management and reducing redundancy.
