Why use a DBMS instead of a File System?

File Systems have a few disadvantages:

• data redundancy and inconsistency

• difficulty in accessing data (need to write a separate program for each task)

• data isolation (multiple files and formats without interrelation)

• integrity problems (hard to create new constraints and manage existing ones)

• non-atomic transactions (all-or-none property not followed)

• issues with concurrent access by multiple users leading to inconsistencies

• security problems

Using a DBMS instead would address these issues.
