Database Approach vs. Traditional File Processing

• Self contained nature of database systems (database contains both data and meta-data).
• Data Independence: application programs and queries are independent of how data is actually stored.
• Data sharing.
• Controlling redundancies and inconsistencies.
• Secure access to database; Restricting unauthorized access.
• Enforcing Integrity Constraints.
• Backup and Recovery from system crashes.
• Support for multiple-users and concurrent access.
