A DBMS or Database Management System is an application which is used to managing and creating databases. With the help of DBMS, the developers and programmers can systematically retrieve, update, manage and create data. It is with the help of a DBMS, it becomes possible for an end user to read, create and update data in the database. It acts as an interface between the application programs or end users and the database. It ensures that the data can be accessed
easily and is organized in a proper manner.
What does DBMS do?
There are 3 important functions that a DBMS manages, they are as:
- The Data
- The database engine which allows the data to be locked, accessed and modified
- The database schema that helps to define the logical structure of a database.
These 3 elements help to provide security, concurrency, data integration, and proper administrative procedures. The different tasks that are supported by a DBMS are
- Change Management
- Performance Tuning/ Monitoring
- And Recover/Backup
There are certain DBMS which performs the task of automated rollbacks, recovery along with auditing of different activities.
When it comes to providing centralized access to the data, DBMS is the best option. It allows the data to be accessed by many users from different locations. With the help of a DBMS, it is possible to limit the access of data to the end users
What are the Advantages of a DBMS?
There are many advantages which a DBMS has to offer when it comes to storing data. One of the major benefits is the fact that it allows the application programmers and the end users to use and access the same data while making sure that the data integrity is being maintained. DBMS ensures better data protection and maintenance.
Here are some of the benefits it has to offer
- Independence and Data Abstraction
- Data Security
- The locking mechanism in order to facilitate concurrent access
- Robust and strong data integrity
- Auditing and logging of activity
- Getting simple access by using an API or Application Programming Interface
Another benefit of DBMS is the fact that it is used to impose a structured, logical organization.
With the help of DMBS, it is possible to achieve the Economy of Scale when it comes to processing
data which are in large volume
