-Poor utilization of database storage space which might be minimal. Large storage
space requirements.
-Problem of securing all the redundant data. Though the data in such a database
is redundant, it must still be secured from unauthorized access. This task is very
difficult to implement because each functional area of an organization holds the
data.
-Confusion – since data is collected and maintained in so many different places, the same
data may have different means in different parts of an organization.
-Difficulty in performing updates – to update a redundant data item, one must
update all instances of the redundant item in all the department files of an
organization. This is clearly hectic.
- Compromised system integrity.Effectiveness of the inbuilt security procedures in the system.
- The error rates for input data.
- The output i.e. whether it is correct, timely and distributed correctly to the relevant
users.
