While denormalization of a database can improve performance, what can denormalization increase the risk of?
A loss of data integrity.
Unauthorized access to data.
Deadlocks.
Concurrent access.
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. EDIT: 2 good answers here.
