Advantages of Database Management System (DBMS)
What is meant by a database management system?
A database management system (DBMS) is essentially a group of linked data and a collection of computer applications and tools that retrieve, analyze, and alter data. By taking the necessary security precautions, it permits access to, recovery of, and use of that data. Better data integration and security can be achieved with the help of a database management system (DBMS).
Advantages of Database Management System
Some of the great advantages of DBMS are listed below:
- Better use of data or information - We can easily and efficiently access well-managed and synchronized forms of data with the help of DBMS. It makes data handling simple, provides an integrated perspective of how a certain business is operating and also aids in keeping track of how one element of the business affects another portion.
- Secured Data - The likelihood of security problems increases as a database becomes more functional and accessible. The danger to data security rises as a result of the rate at which data is shared or transferred growing along with the user base. It is frequently utilized in the business world where organizations spend a lot of time, money, and effort making sure data is protected and handled effectively. Data management systems (DBMS) offer a stronger framework for data privacy and security policies, assisting businesses in enhancing data security.
- Reduces Data Inconsistency and Redundancy - The major issues faced during the process of storing data are inconsistency and redundancy. Inconsistent data may lead to a big loss to an individual or a business model and the storage capacity is not utilized properly because of the data redundancy. When multiple copies with different versions or values of the same data exist in various locations, then it causes inconsistency. Data Redundancy and inconsistency can both be significantly decreased by properly designing a database with the help of a database management system.
- Better Recovery and Backups - Backup and recovery are handled automatically by the DBMS. Users don't need to regularly back up their data because the DBMS handles this for them. Additionally, it returns the database to its prior state following a crash or system failure.
- Fast Data Sharing - Database administration makes it possible for consumers to access more and better-managed data. DBMS enables end users to quickly scan their environment and react to any alterations made there.
- Helps in decision-making - Because of the well-managed data and improved data access provided by DBMS, we are able to produce better-quality information and, as a result, make better judgments. Accuracy, validity, and the time it takes to read data are all improved by better data quality. Although DBMS does not ensure data quality, it does offer a framework that makes it simple to enhance data quality.
- Increases Privacy - The privacy rule in a database specifies the privacy restrictions that can only be accessed by authorized users. A user can only view the data he is permitted to view since there are different degrees of database access. For instance, on social networking sites, different accounts that a user wishes to access have varying access restrictions and a user can only see his/her account details, not others.
- User Friendly - Data are presented in a straightforward and logical manner by database management systems (DBMS). It is simple to carry out many activities, such as the addition, deletion, or creation of files or data.
- Data Abstraction - In order to give users an abstract overview of the data, database systems are primarily used. Since numerous intricate algorithms are employed by developers to boost the effectiveness of databases that are concealed from users by several degrees of data abstraction, consumers can easily engage with the system.
In simple words, DBMS reduces data inconsistency and redundancy, increases data security and privacy, and provides a platform to access and share data faster.
