Advantages of DBMS (Database Management System):
Data Integration: Integration of data from multiple sources into a single, centralized database.
Data Consistency: Maintains data consistency across the entire database, even when multiple users access the same data simultaneously.
Data Security: Enables the creation of user accounts with specific permissions, which helps to secure data.
Data Backup and Recovery: Automated backup and recovery processes ensure that data can be recovered in the event of a disaster or system failure.
Data Abstraction: Hides the complexities of data storage and retrieval behind a simple, user-friendly interface.
Data Sharing: Enables multiple users to access the same data simultaneously, facilitating collaboration and data sharing.
Disadvantages of DBMS:
Cost: Implementing a DBMS can be expensive, requiring hardware, software, and personnel costs.
Complexity: The use of a DBMS requires a certain level of technical expertise, which can make it difficult for non-technical users to access and manipulate data.
Performance Overhead: The use of a DBMS can result in a performance overhead, as data must be passed through multiple layers to reach the end user.
Dependency: A DBMS creates a dependency on the database for all data storage and retrieval, making it more difficult to switch to a different system if necessary.
Limited Flexibility: The use of a DBMS can limit the flexibility of data storage and retrieval, as the system is designed to meet specific requirements.
