File system was used in the earlier years but has now been replaced by modern database management system. Data used to be stored in physical files since technology had not yet evolved. Traditional filing system had many challenges which majority are solved by the modern database management system.
Features of modern database management system.
1. Elimination of redundancy.
The modern DBMS does not allow repetition and storage of the same data.
2. Saves on cost and space.
DBMS is an efficient system that manages storage space and hence stores large data in a small storage space and hence minimizes cost of storage.
3. Data security improvement.
Users are required to take part in the process of authentication and verification as measures of system security before they are allowed access to the database. This minimizes Intruders from accessing data that does not belong to them.
4. Availability of data.
Authorised entities or personnel can access data anytime once they have verified their identity.
5. Acccuracy and consistency of data.
DBMS system is accurate when carrying out the input of data and hence does not allow data which has errors or inaccurate to be stored.
6. Easy management of data.
DBMS consists of tools that help the users on how to manage their data as to their requirements.
