Define Database
A database is an organized collection of related data stored in a structured way so that it can be easily accessed, managed, updated, and retrieved using a Database Management System (DBMS). It allows users and applications to handle large amounts of information efficiently.
Advantages of Database Over File-Based System
-
Reduced Data Redundancy
In a database, data is stored centrally, preventing unnecessary duplication. File-based systems often store the same data in multiple files. -
Improved Data Consistency
Since redundancy is minimized, the chances of having inconsistent or conflicting data are very low compared to file-based systems. -
Better Data Security
Databases provide controlled access with usernames, passwords, permissions, and encryption. File-based systems lack strong security mechanisms. -
Data Sharing and Multi-user Support
Multiple users can access and update data simultaneously without conflict. File-based systems struggle with multi-user access. -
Backup and Recovery
Databases offer automatic backup and recovery tools to protect data from loss. File systems require manual backup, increasing risk. -
Enhanced Data Integrity
Databases use rules, constraints, and relationships to maintain accuracy and reliability of data. File-based systems do not enforce such rules.
