Introduction to database systems - Characteristics of database approach - Advantages of using DBMS approach
Remember the key characteristics of the database approach: Self-describing nature (metadata), program–data independence, multiple user views, and data sharing with concurrent access
Focus on the major advantages of DBMS over the file system: Reduced data redundancy, improved data consistency, enhanced security, backup & recovery, and support for multiple users.
Be able to differentiate between a Database, DBMS, and File System with at least 2–3 comparison points.
Practice scenario-based questions, such as why organizations prefer DBMS over file systems or how DBMS reduces redundancy and improves data integrity.
Discuss the main characteristics of the database approach and how it differs from traditional file systems.
What is Data Abstraction? Explain about different views of data.
Distinguish the main characteristics of database approach from the much older approach of managing data with traditional file processing system.
Why would you choose database system instead of simply storing data in operating system files? When would it make sense not to use a database system?
Explicate the key characteristics of the database management system that distinguish it from traditional file-processing systems. Illustrate each characteristic with suitable examples.
