why database shouldn't be used instead of filling system?
Answers
Answer:
File processing system has more data redundancy, less data redundancy in dbms. File processing system provides less flexibility in accessing data, whereas dbms has more flexibility in accessing data. File processing system does not provide data consistency, whereas dbms provides data consistency through normalization
Explanation:
Overhead for providing generality, security, concurrency control, recovery, and integrity functions. When a DBMS may be unnecessary: If the database and applications are simple, well defined, and not expected to change. If there are stringent real-time requirements that may not be met because of DBMS overhead.
data normalization. ... Easy recovery: Since database systems keeps the backup of data, it is easier to do a full recovery of data in case of a failure. Flexible: Database systems are more flexible than file processing systems.
