1)Data Redundancy and Consistency
File System: Data redundancy is common as there is no centralized control, leading to duplicate data across files. Consistency is challenging to maintain.
DBMS: Minimizes redundancy by allowing centralized data control, ensuring that data is consistent and synchronized across applications.
2)Data Access and Retrieval
File System: Data retrieval is less efficient and often requires complex custom programming, as there’s no standardized query language.
DBMS: Provides efficient data retrieval using SQL (or other query languages), enabling complex queries and fast access without custom code.
3)Data Security
File System: Offers limited security, often restricted to simple access controls or file permissions.
DBMS: Provides robust security features like user authentication, role-based access control, and encryption to secure sensitive data.
4)Data Integrity
File System: Ensuring data integrity is manual and difficult; inconsistent data entries can easily occur.
DBMS: Enforces integrity constraints to ensure data accuracy and validity (e.g., primary keys, foreign keys), thus ensuring data integrity across the database.
5)Concurrent Access and Transaction Management
File System: Managing concurrent access to files is challenging and can lead to issues like data corruption if multiple users try to modify a file simultaneously.
DBMS: Allows multiple users to access and manipulate data concurrently using ACID properties, ensuring data consistency and integrity during transactions.
6)Backup and Recovery
File System: Backup and recovery processes are typically manual, making it harder to recover data in case of failure.
DBMS: Offers automated backup and recovery features, making it easy to restore the database to a previous state in case of system failure or data loss.
7)Data Structure
File System: Data is stored in files without a predefined structure; it’s often unstructured and varies between applications.
DBMS: Data is stored in a structured format using tables, schemas, and relationships, making data organized and easier to manage.
8)Scalability
File System: Limited scalability; as data grows, managing files becomes increasingly complex and inefficient.
DBMS: Designed to scale efficiently with large datasets, supporting features like indexing and optimized queries for better performance with growing data.
9)Data Sharing
File System: Data sharing is difficult, often requiring duplication and increasing chances of inconsistencies.
DBMS: Enables efficient data sharing across multiple applications, making it ideal for multi-user environments.
10)Complexity and Cost
File System: Simpler to implement and maintain with low cost, suitable for small applications.
DBMS: More complex and costly due to specialized software, hardware, and technical expertise, but essential for large-scale data management.
In general, file systems are best suited for simple storage needs, while DBMS is ideal for complex data management, data consistency, and multi-user access in large systems.
