Advantages of DBMS

A Database Management System (DBMS) is a collection of programs which lets the end-users to manage and control the database.

Database systems use query language for accessing, storing, and maintaining the data in the databases. DBMS is a layer presenting between the program and the data. Data security is the best feature of the database systems.

Various advantages or benefits of the database management system are discussed below:

1. Simple

The database management system is simple to understand for its users. It gives a clear conceptual or logical view of the specified data. In the database systems, the user can easily implement the insert and delete operations on the specified data. 

2. Data Redundancy

Redundancy of the data is the first advantage of the database systems. In the database systems, duplicacy of data is eliminated or removed because the whole data is stored at a centralized location. So, there is no data redundancy in the database systems.

3. Data Consistency

If there is no data redundancy in the database systems, then the data consistency automatically maintains. Data consistency occurs when the two values are entered for the same data in the database.

As the data is centralized, so the updated data is same for all those users who access it. That’s why the consistency of the data is also maintained in the database management systems.

4. Data Integrity

Data integrity says that the data is consistent as well as accurate for all the database users in the database systems. Database systems provide various integrity constraints for maintaining data integrity.

5. Data Security

It is the main advantage which allows users to use it. Database systems provide high security to the data. A database system also provides various security policies.

The data security features of DBMS allow only authorized users to access the confidential and necessary data of an organization. DBMS provides the username and password to the users to use their databases.

6. Data Backup and Recovery

In today’s time, data loss is a big problem for all companies and organizations. So, DBMS provides a strong framework for data backup and recovery.

In database systems, the user does not need to back up their data manually, as it allows automatic backup and recovery of the database.

If any system fails or crashes due to some reason, DBMS restores the database to its previous condition by this concept.

7. Data Sharing

Sharing of the data is also another important benefit of the database management systems. Using a DBMS environment, end-users can easily share confidential data or information among themselves.

It also allows data sharing for those users who work from remote locations.

8. Concurrency Control

In database systems, concurrency control means the execution of multiple transactions at the same time. DBMS provides the various concurrency control protocols for ensuring the atomicity and serializability of the concurrent data access.

9. Low Maintenance Cost of DBMS Software

The cost of setting up the database systems might be high, but their maintenance cost is very less. After purchasing the database systems, users do not need large money to maintain them.

10. Data Abstraction

Database systems abstract those data and information from the users, which are not useful for the end-users. These systems show the necessary data to the users.

11. Support Multi-Access

Database systems lets multiple users to access the same data from different locations at the same time. Due to this, the working speed on the database is increase.
