Benefits And Drawbacks Of Using A Database Management System
A database management system (DBMS) is a set of programmes that manages the database structure and controls access to the data contained inside. It serves as the medium between the user and the database. Commercial database management systems include Oracle, SQL servers, FoxPro, base, and IMS.
Let's understand the advantages and disadvantages of a database management system (DBMS).
Advantage of DBMS
Sharing data
In terms of data sharing among end-users, the DBMS provides a user-friendly environment. Users can manage and access data simultaneously in this setting, ensuring that any changes in the database make instant communication to the user.
Security
For any business, data is critical. A database management system (DBMS) provides a framework for more effectively enforcing data privacy and security regulations. Many database management systems have authentication techniques built-in, such as login username and password.
Accessibility
DBMS allows users to access the required information without presenting irrelevant records directly. Each data in DBMS categorizes to makes them easy to classify. And also, in DBMS, multiple users will be able to access the database and share relevant information.
Consistency
The odds of data inconsistency decreases to a greater extent due to the centralized system in DBMS. A database management system may have several file formats for the same data in some cases. The DBMS system efficiently accomplishes this by regulating any number of data redundancies present on the system.
Data Backup
In a hardware or software failure, the DBMS is always responsible for backing up the data. As a result, users are relieved of the responsibility of regularly backing up their data. In addition, if the system fails, the DBMS returns the system to its previous state automatically.

Cost
The DBMS software connects functions on automatic machines, necessitating a sophisticated system with plenty of memory and processing capacity. To support programmes for various operations, the hardware needs to be regularly updated. Furthermore, both the hardware and software require professional maintenance, which might result in additional costs.
Reliability
Because the entire structure is dependent on the database, a database management system is more prone to failure. Any harm to the database could cause all of the application programmes to stop working. Even if one of the components fails, the entire operation will come to a halt.
Maintenance
In addition to management, a database management system needs to be maintained regularly to keep the system current. Users can only obtain the optimum efficiency of a database system by staying current. However, because maintenance requires a substantial amount of money, this is not a simple process.
Complexity
A database management system (DBMS) is a complicated piece of software. The engagement of functions from several companies adds to the complexity. As a result, they are tough to comprehend for all developers, administrators, and users. Finally, failing to understand means a considerable risk of database failure and data loss.
Upgradation
It is also vital to upgrade the system regularly to stay current with technology and associated improvements. New hardware components are necessary for installation at some point throughout the upgrade process. Even though the system gets an upgrade, adapting to the changes is difficult. Furthermore, to combat emerging threats, regular upgrades are necessary.
