Anomalies are problems which arises when changes are made to
the database.
There are three types of anomalies:
>INSERTIN-This problem occurs due to inability to represent
a certain information example;when information about new
cannot be inserted in a DB,
>DELETION-This occurs due to loss of useful information
Example;when we delete information in a DB we will loss
relevant information.
>UPDATE-This type occurs due to redundant information make
difficult to update
