A database administrator has detected a performance problem with some tables which could be solved through denormalization. This situation will increase the risk of: A. concurrent access. B. deadlocks. C. unauthorized access to data. D. a loss of data integrity.
Correct Answer: D
Explanation:
Explanation:
Normalization is the removal of redundant data elements from the database structure. Disabling normalization in relational databases will create redundancy and a risk of not maintaining consistency of data, with the consequent loss of data integrity. Deadlocks are not caused by denormalization. Access to data is controlled by defining user rights to information, and is not affected by denormalization.
