Disadvantages of file processing system

Disadvantages of file processing system:-
a.)Data redundancy and inconsistency.:-Data redundancy means duplication of data.Non data base system maintain separate copy of data for each applied redundancy leads to higher storage and access cost.and also inconstancy.
b.)Difficulty in accessing data.:-file-processing environments do not allow needed data to be retrieved in a convenient and efficient manner.
c.)Data isolation.:- Because data are scattered in various files, and files may be in
different formats, writing new application programs to retrieve the appropriate
data is difficult.
d.)Integrity problems.:- The data values stored in the database must satisfy certain
types of consistency constraints.when new constraints are added, it is difficult
to change the programs.
e.)Atomicity problems.:-the funds transfer must be atomic—it must happen in its entirety or
not at all. It is difficult to ensure atomicity in a conventional file-processing
system.
f.)Concurrent-access anomalies.:-It not provide it.
g.)Security problems:-enforcing security constraints is difficult.
