Problems with Tradional Data base approach

Data Redundancy
As applications and their data files were created by different programmer over a period of time, the same piece of information could be duplicated in several places. Resulting in overconsuming of space
Data inconsistency:
Means that the various copies of the data no longer agree.
Data Isolation:
It also leads ro difficulty in accessing data from different applicatiob
Security:
is difficult to enforce in the file environment beacuse new applications may be added to the system on an ad-hoc basis and with more applications more people have access to data
