Update Anomaly: This anomaly is occurred due to data redundancy. Redundant information makes updates more complex since, for example, varying the name of the instructor of MCS-014 would need that all tuples having MCS-014 enrolment information be updated.

This problem is known as update anomaly. An update anomaly results in data inconsistency.
