File system Versus DBMS |Introduction to Database management system


Also known as traditional file processing system.File processing systems was an early attempt to computerize the manual filing system that we are all familiar with. A file system is a method for storing and organizing computer files and the data they contain to make it easy to find and access them.
                            File systems may use a storage device such as a hard disk or CD-ROM and involve maintaining the physical location of the files. EG- In BANK there is a file name "accounts file".If anyone wants to search they have the ability to search the accounts of all users.

Characteristics of File Processing System:-
1.) It is a group of files storing data of an organization.
2.) Data stored in the simple files known as flat files.
3.) Data is stored in hard-disk or any CD-ROM.
4.) Each file is independent from one another.
(File Management System)

DBMS:-A DBMS is a collection of programs that enables users to create and maintain a database.The DBMS is a general purpose software system that facilitates the process of defining,constructing manipulating and sharing databases among various users and applications.Defining a database involves specifying the data types,structures and constraints of the data to be stored in the database.Only user can access his own data.

ADVANTAGE-The advantages of DBMS are:-
2. Non-redundancy
3. Consistency
4. Correctness Isolation
