File System vs. DBMS: Core Differences
📌 The File System was the traditional method before DBMS, primarily used when users managed their own data in localized structures (files, folders, hierarchical storage).
🖥️ DBMS is essential for client-server architectures where data is centralized on a server and accessed globally by many users simultaneously.
📂 The file system relies on the operating system (like CIFS, NFS) for basic organization, lacking advanced data management features found in DBMS.
Advantage 1: Data Searching and Efficiency
🔍 File systems retrieve entire files, even when only a small piece of data (e.g., 1 KB query result) is needed, potentially transferring massive amounts of data (e.g., 25 GB example).
📜 DBMS allows users to write simple SQL queries to retrieve *only* the required subset of data (e.g., 1 KB), leading to faster searching and efficient memory utilization.
Advantage 2: Data Access and Abstraction
🛑 File system access requires knowing specific metadata like file name and exact location (e.g., C:/folder1/folder2).
🌐 DBMS offers location independence; users access data via a platform (web/mobile app) without needing to know the physical storage attributes.
Advantage 3: Concurrency Control
⏱️ File systems lack protocols for concurrent access, risking data inconsistency when multiple users try to read/write simultaneously (e.g., IRCTC handling 1k-2k transactions at a time).
🛡️ DBMS provides dedicated concurrency protocols (handling read-read, read-write, write-read, write-write scenarios) to manage simultaneous user operations reliably.
Advantage 4: Security and Access Control
👤 File system security is generally limited to OS-level login passwords, offering no fine-grained control over who accesses specific internal data.
🔑 DBMS implements Role-Based Access Control (RBAC), creating distinct user roles (Student, Faculty, Dean) to ensure users only see data relevant to their permissions.
Advantage 5: Data Redundancy and Integrity
🔁 File systems allow data duplication easily if files are named differently, leading to data redundancy.
✅ DBMS utilizes constraints like primary keys and foreign keys to enforce data integrity and prevent unnecessary data duplication.
Key Points & Insights
➡️ For modern, global applications utilizing client-server models, DBMS is mandatory over traditional file systems due to its robust data handling capabilities.
➡️ The shift to DBMS provides significant performance benefits by restricting data transfer to only the required results via querying instead of transferring entire files.
➡️ Role-based security in DBMS is crucial for complex organizational data management, which file systems cannot effectively replicate.
