Data Inconsistency: Data inconsistency means that different files may
contain different information of a particular object or person. Actually
redundancy leads to inconsistency. When the same data is stored in multiple
locations, the inconsistency may occur.
Data Sharing: In computer file-based processing systems, each
application program uses its own private data files. The computer file-based
processing systems do not provide the facility to share data of a data file
among multiple users on the network.
Data Isolation: In computer file-based system, data is isolated in
separate files. It is difficult to update and to access particular information
from data files
