Advantages of DBMS:

  1. No Data Duplication:
    • Advantage: DBMS prevents the same data from being stored in multiple places, reducing redundancy and ensuring data consistency.
  2. Data Sharing:
    • Advantage: Authorized users can easily share and access data, promoting collaboration within an organization.
  3. Easy Maintenance:
    • Advantage: DBMS is centrally managed, making it easier to update and maintain data, reducing the workload on individual users.
  4. Time Savings:
    • Advantage: Development time is reduced as DBMS provides tools and features to efficiently handle data, improving productivity.
  5. Backup and Recovery:
    • Advantage: Automatic backup systems protect data from hardware or software failures, and quick recovery options help restore lost data.
  6. Multiple User Interfaces:
    • Advantage: DBMS offers different interfaces, such as graphical and application program interfaces, making it accessible to various users.

Disadvantages of DBMS:

  1. Cost of Hardware and Software:
    • Disadvantage: Running a DBMS requires powerful hardware and software, which can be expensive.
  2. Large Size:
    • Disadvantage: DBMS occupies significant disk space and memory, demanding substantial resources for efficient operation.
  3. Complexity:
    • Disadvantage: Implementing and managing a database system adds complexity to the overall IT structure.
  4. Higher Impact of Failure:
    • Disadvantage: If a database fails due to issues like power outages or corruption, it can lead to significant data loss since all data is stored in a centralized database.
