DBMS
A computerized record-keeping system

File System
A collection of individual files accessed by applications programs.

Limitations File System Databases

• Separated and Isolated Data makes access, update and management difficult
• Data Duplication - Wastes space and can lead to data integrity (inconsistency) problems
• Depends on Application Program - Changes to a single file require changes to programs
• Incompatible Files on different systems
• Not standardized = private standards by applications

Advantages of a DBMS

• Minimize data duplication
• Independence of Application programs
• Data stored in a uniform structure
• Data sharing is concurrent
• Increased Security and Privacy
• Multiple views of same data
• Expandability, Flexibility, Scalability
• Reduced application development time
• Standards enforcement
