Why database system are needed to replace the file based?

Database systems are needed to replace file-based systems because they provide improved data integrity, consistency, and security through structured data management. Unlike file-based systems, databases allow for efficient querying, data manipulation, and concurrent access by multiple users without risk of data corruption. Additionally, they support complex relationships between data entities, enabling more advanced data analysis and reporting capabilities. Overall, databases enhance scalability and maintainability, making them more suitable for modern applications.
