Normalization is the removal of redundant data elements from the database structure. Disabling features of normalization in relational databases will increase the likelihood of data redundancy. Audit trails are a feature of DBMS software that can be lost by not enabling them. These are not connected to normalization controls. The integrity of data is not directly affected by disabling normalization controls. Access to data is set through defining user rights and controlling access to information, and is not affected by normalization controls.
