Question

which of the following best describes data normalization?

one of the main methods of social media monitoring
the process of getting rid of duplicates or mistakes in data
specialized software that keep records of all transactions at a business
computer programs that automatically collect data at the source the data are generated from

Explanation:

Define data normalization

Data normalization is a systematic process used in database design and data management. Its primary goal is to organize data efficiently by reducing redundancy and eliminating anomalies, which helps in getting rid of duplicate entries and correcting structural mistakes.

Analyze the given options

• Option 1: "one of the main methods of social media monitoring" — This is incorrect, as normalization is a general data management process, not a social media monitoring tool.
• Option 2: "the process of getting rid of duplicates or mistakes in data" — This aligns with the core purpose of normalization, which is to eliminate redundant (duplicate) data and ensure data integrity (preventing mistakes).
• Option 3: "specialized software that keep records of all transactions at a business" — This describes a Transaction Processing System, which is already in your Database Management System knowledge base, not normalization itself.
• Option 4: "computer programs that automatically collect data at the source..." — This describes automated data collection methods rather than normalization.

Determine the correct choice

Option 2 is the most accurate description among the choices provided, as organizing database tables to eliminate redundancy directly prevents duplicate records and structural inconsistencies.

Answer:

• (A) one of the main methods of social media monitoring
• (B) the process of getting rid of duplicates or mistakes in data (Correct answer)
• (C) specialized software that keep records of all transactions at a business
• (D) computer programs that automatically collect data at the source the data are generated from
