Before databases were introduced, data was stored in files such as text files or spreadsheets.
Managing large amounts of data using files becomes difficult, slow, and unsafe.
As applications grow, file-based systems cannot handle data efficiently.
Databases allow data to be stored in a structured format.
This structure helps applications quickly search and retrieve required information.
Using databases reduces duplication and improves data organization.
One major problem with file systems is data inconsistency.
The same data may exist in multiple files with different values.
Databases solve this problem by storing data in a centralized location.
Databases also provide security.
Access can be controlled so that only authorized users can read or modify data.
This is very important in applications such as banking, e-commerce, and enterprise systems.
Databases improve performance when working with large data.
They allow fast searching, sorting, and filtering of records.
Because of these advantages, databases are used in almost all modern software systems.
