If database is not designed well, it exhibits following problems called Update Anomaly. there different types of anomaly exists and they are as follows: Insertion anomaly: It is difficult to insert required data as not availability of other data. Deletion anomaly: We can not delete unnecessary data cause as we delete those data necessary data will also be deleted.
