File System

DBMS
A software that manages and organizes the file in storage medium is called as file system. DBMS is  software application that is used for creating, accessing and managing databases.
Data Storage and Data representation details is provided by the file system Data that hides the details is given an abstraction in DBMS.
Storing and retrieving data cannot be done efficiently in this system. A wide variety of methods to store data and retrieve data can be done efficiently through DBMS.
Data Recovery process is not possbile In DBMS Data Backup Recovery is possible.
File system does not have a crash recovery mechanism It provides crash recovery mechanism.
Protecting a file system is very difficult Offers good protection mechanism
Redundancy of data is greater in file system Redundancy of data is lower in DBMS
File system has a higher data inconsistency DBMS has a lower data inconsistency
File system offer less security DBMS offer higher security
File System allows you to stores the data as isolated data files and entities. Database Management System stores data as well as defined constraints and interrelation.
Support for complicated transactions is not supported Easy to implement complicated transactions.
The centralization process is hard in File Management System. Centralization is easy to achieve in the DBMS system.
Back up and recovery of data is not possible if the data is lost. DBMS system provides backup and recovery of data even if it is lost.
No efficient query processing in file system You can easily query data in a database using the SQL language.
This system doesn’t offer concurrency. DBMS system provides a concurrency facility.

DBMS

RDBMS
Data is stored in file format Data is stored in table format.
Data is stored either in a hierarchical form or navigational form  Tables have an identifier called primary key, and data values are stored in the form of tables.
No Normalization is present. Normalization is present in RDBMS.
Do not provide security for data manipulation RDBMS defines the integrity constraint for the purpose of ACID (Atomocity, Consistency, Isolation and Durability) property.
Uses file system to store data, so there will be no relation between the tables  In RDBMS since the data values are stored in the form of tables, relationship between these data values will also be stored in the form of table.
Provides some methods to access the stored information. For accessing the stored information RDBMS supports a tabular structure of the data and relationship between them
Does not support distributed data base. RDBMS supports distributed database.
It is meant for small organization and deal with small data. Supports single user. RDBMS is designed to handle large amount of data. it supports multiple users.
Examples of DBMS are file systems, xml Example of RDBMS are mysql, postgre, sql server, oracle etc.
