Quizplus · Accepted Answer

An update anomaly occurs when a change is made to one record in a database, but the change is not correctly or completely updated in all other related records, resulting in inconsistencies and errors in data. Insert anomalies occur when a record cannot be added to a database because its related data is incomplete, and delete anomalies occur when deleting a record unintentionally removes related data as well. Memory anomaly is not a recognized database term.
