2. 1 Introduction to File System and DBMS A file system is a method used for storing and organizing files on a storage medium. A database management system (DBMS) is a software system that allows for the creation, maintenance, and utilization of databases. File systems are typically used for small-scale data storage, while DBMS is designed for large-scale data management.

3. 2 Structure of File System In a file system, data is stored in files and directories in a hierarchical structure. Users have direct control over the organization and access of files in a file system. File systems do not provide mechanisms for data consistency, integrity, and security.

4. 3 Structure of DBMS DBMS organizes data in tables, rows, and columns within a database. DBMS offers data independence, allowing changes in the database structure without affecting the application programs. DBMS provides features such as data integrity constraints, transactions, and access control mechanisms.

5. 4 Data Retrieval in File System In a file system, data retrieval involves searching through directories and files to locate the desired information. File systems require manual handling of data retrieval processes, leading to inefficiencies. File systems lack query languages for efficient data retrieval.

6. 5 Data Retrieval in DBMS DBMS utilizes SQL (Structured Query Language) to retrieve data efficiently from databases. DBMS supports complex queries involving multiple tables and conditions for data retrieval. DBMS optimizes data retrieval through indexing and query optimization techniques.

7. 6 Data Redundancy in File System File systems often lead to data redundancy as the same data may be stored in multiple files. Data redundancy in file systems can result in inconsistencies and wastage of storage space. File systems do not provide mechanisms for enforcing data normalization and reducing redundancy.

8. 7 Data Redundancy in DBMS DBMS reduces data redundancy through normalization techniques that minimize duplicate data. DBMS enforces data integrity constraints to maintain consistency and accuracy of data. DBMS supports relationships between tables to avoid redundancy and ensure data consistency.

9. 8 Data Security in File System File systems provide limited data security features such as file permissions and access controls. Data security in file systems relies heavily on the discretion of users and administrators. File systems lack robust security mechanisms such as encryption and role-based access control.

10. 9 Data Security in DBMS DBMS offers advanced security features including encryption, authentication, and authorization mechanisms. DBMS enforces access control policies to restrict unauthorized access to sensitive data. DBMS ensures data confidentiality, integrity, and availability through security measures.

11. 10 Scalability and Performance File systems are suitable for small-scale data storage but may face performance issues with large datasets. DBMS is designed for scalability, allowing efficient management of large volumes of data. DBMS offers performance optimization features such as indexing and query optimization for enhanced speed.
