Anomalies are problems that arise in the data due to a flaw
in the database design. There are three types of anomalies….
*Insertion Anomalies:Insertion anomalies occur when we
try to insert data into a flawed table.
*Deletion Anomalies:- Deletion anomalies occur when we
delete data from a flawed schema.
*Update Anomalies:- Update anomalies occur when we
change data in a flawed schema.

Anomalies are problems which arises when changes are made to
the database.

a certain information example;when information about new
