Database Management System (DBMS) is a collection of interrelated data and a set of software tools/programs that access, process, and manipulate data. It allows access, retrieval, and use of that data by considering appropriate security measures. The Database Management system (DBMS) is really useful for better data integration and security.
Advantages of DBMS
Advantages of Database Management System
Some of them are given as follows below.
- Better Data Transferring: Database management creates a place where users have an advantage of more and better-managed data. Thus making it possible for end-users to have a quick look and to respond fast to any changes made in their environment.
- Better Data Security: The more accessible and usable the database, the more it is prone to security issues. As the number of users increases, the data transferring or data sharing rate also increases thus increasing the risk of data security. It is widely used in the corporate world where companies invest large amounts of money, time, and effort to ensure data is secure and used properly. A Database Management System (DBMS) provides a better platform for data privacy and security policies thus, helping companies to improve Data Security.
- Better data integration: Due to the Database Management System we have access to well-managed and synchronized forms of data thus it makes data handling very easy and gives an integrated view of how a particular organization is working and also helps to keep track of how one segment of the company affects another segment.
- Minimized Data Inconsistency: Data inconsistency occurs between files when different versions of the same data appear in different places. For Example, data inconsistency occurs when a student’s name is saved as “John Wayne” on the main computer of the school but on the teacher registered system same student name is “William J. Wayne”, or when the price of a product is $86.95 in the local system of the company and its National sales office system shows the same product price as $84.95. So if a database is properly designed then Data inconsistency can be greatly reduced hence minimizing data inconsistency.
-
Faster data Access: The Database management system (DBMS) helps to produce quick answers to database queries thus making data access faster and more accurate. For example, to read or update the data. For example, end-users, when dealing with large amounts of sale data, will have enhanced access to the data, enabling a faster sales cycle. Some queries may be like:
- What is the increase in sales in the last three months?
- What is the bonus given to each the salespeople in the last five months?
- How many customers have a credit score of 850 or more?
- Better decision making: Due to DBMS now we have Better managed data and Improved data access because of which we can generate better quality information hence on this basis better decisions can be made. Better Data quality improves accuracy, validity, and the a time it takes to read data. DBMS does not guarantee data quality, it provides a framework to make it easy to improve data quality. DBMS provides powerful data analysis and reporting tools that allow users to make informed decisions based on data insights. This helps organizations to improve their decision-making processes and achieve better business outcomes.
- Increased end-user productivity: The data which is available with the help of a combination of tools that transform data into useful information, helps end-users to make quick, informative, and better decisions that can make a difference between success and failure in the global economy.
- Simple: Database management system (DBMS) gives a simple and clear logical view of data. Many operations like insertion, deletion, or creation of files or data are easy to implement.
- Data abstraction: The major purpose of a database system is to provide users with an abstract view of the data. Since many complex algorithms are used by the developers to increase the efficiency of databases that are being hidden by the users through various data abstraction levels to allow users to easily interact with the system.
- Reduction in data Redundancy: When working with a structured database, DBMS provides the feature to prevent the input of duplicate items in the database. for e.g. – If there are two same students in different rows, then one of the duplicate data will be deleted.
- Application development: A DBMS provides a foundation for developing applications that require access to large amounts of data, reducing development time and costs.
- Data sharing: A DBMS provides a platform for sharing data across multiple applications and users, which can increase productivity and collaboration.
- Data organization: A DBMS provides a systematic approach to organizing data in a structured way, which makes it easier to retrieve and manage data efficiently.
-
The atomicity of data can be maintained: That means, if some operation is
performed on one particular table of the database, then the change must be reflected for the entire database. - The DBMS allows concurrent access to multiple users by using the synchronization technique.
- Data consistency and accuracy: DBMS ensures that data is consistent and accurate by enforcing data integrity constraints and preventing data duplication. This helps to eliminate data discrepancies and errors that can occur when data is stored and managed manually.
- Improved data security: DBMS provides a high level of data security by offering user authentication and authorization, data encryption, and access control mechanisms. This helps to protect sensitive data from unauthorized access, modification, or theft.
- Efficient data access and retrieval: DBMS allows for efficient data access and retrieval by providing indexing and query optimization techniques that speed up data retrieval. This reduces the time required to process large volumes of data and increases the overall performance of the system.
- Scalability and flexibility: DBMS is highly scalable and can easily accommodate changes in data volumes and user requirements. DBMS can easily handle large volumes of data, and can scale up or down depending on the needs of the organization. It provides flexibility in data storage, retrieval, and manipulation, allowing users to easily modify the structure and content of the database as needed.
- Improved productivity: DBMS reduces the time and effort required to manage data, which increases productivity and efficiency. It also provides a user-friendly interface for data entry and retrieval, which reduces the learning curve for new users.
Advantages of Database Management System over Traditional File System
- Data Integrity and Security: DBMS provides a centralized approach to data management that ensures data integrity and security. DBMS allows defining constraints and rules to ensure that data is consistent and accurate.
- Reduced Data Redundancy: DBMS eliminates data redundancy by storing data in a structured way. It allows sharing data across different applications and users, reducing the need for duplicating data.
- Improved Data Consistency: DBMS ensures data consistency by enforcing data validation rules and constraints. This ensures that data is accurate and consistent across different applications and users.
- Improved Data Access and Availability: DBMS provides efficient data access and retrieval mechanisms that enable quick and easy data access. It allows multiple users to access the data simultaneously, ensuring data availability.
- Improved Data Sharing: DBMS provides a platform for sharing data across different applications and users. It allows sharing data between different departments and systems within an organization, improving collaboration and decision-making.
- Improved Data Integration: DBMS allows integrating data from different sources, providing a comprehensive view of the data. It enables data integration from different systems and platforms, improving the quality of data analysis.
- Improved Data Backup and Recovery: DBMS provides backup and recovery mechanisms that ensure data is not lost in case of a system failure. It allows restoring data to a specific point in time, ensuring data consistency.
- Data sharing: DBMSs prevent conflicts and data loss by enabling numerous people to view and edit the same data at once. This promotes teamwork and enhances data uniformity throughout the company.
- Data independence: By separating the logical and physical views of data, database management systems (DBMS) enable users to work with data without being aware of its exact location or structure. This offers adaptability and lowers the possibility of data damage as a result of modifications to the underlying hardware or software.
- Data integrity: To avoid data mistakes and inconsistencies, database management systems (DBMSs) apply data integrity requirements including referential integrity, entity integrity, and domain integrity. This guarantees the consistency, accuracy, and completeness of the data.
- Data security: To prevent illegal access, alteration, or theft, database management systems (DBMS) include a number of security features, including encryption, authentication, and authorization. Sensitive data is safeguarded against both internal and external attacks thanks to this.
- Data backup and recovery: Database management systems (DBMS) offer backup and recovery features that let businesses swiftly and effectively restore lost or damaged data. This guarantees business continuity and lowers the chance of data loss.
- Decreased data redundancy: By keeping data centrally and offering methods for sharing and reusing it, database management systems (DBMS) remove data redundancy. As a result, less data storage is needed, and data consistency is increased.
Conclusion
Overall, Database management System offers several advantages over traditional file-based systems. It ensures data integrity, security, and consistency, reduces data redundancy, and improves data access, sharing, and integration. These benefits make DBMS an essential tool for managing and processing data in modern organizations.
