Database approach benefits Which of the following is NOT a disadvantage, but rather a benefit, of the database approach compared to traditional file systems?
-
Aelimination of the data redundancy
-
Bability to associate related data
-
Cincreased security
-
Dprogram/data independence
-
EAll of the above are advantages
Answer
Correct Answer: All of the above are advantages
Explanation
Introduction / Context: The database approach replaced file-centric processing by introducing centralized schemas, integrity, and controlled sharing. Recognizing genuine benefits avoids misclassifying strengths as weaknesses when evaluating architectures or explaining DBMS value to stakeholders.
Given Data / Assumptions:
- Options list classic benefits of databases.
- The prompt asks for what is NOT a disadvantage (i.e., is actually positive).
- We assume standard DBMS capabilities such as constraints, indexes, transactions, and permissions.
Concept / Approach: Databases reduce redundancy by centralizing data; they enable rich associations via keys and joins; they enhance security with roles, privileges, and auditing; and they provide program/data independence by abstracting physical storage behind schemas and views. Therefore, all listed items are advantages, not disadvantages.
Step-by-Step Solution:
Check each option against known DBMS benefits.Confirm that none are disadvantages of the database approach.Select “All of the above are advantages.”Document why each is beneficial.Verification / Alternative check: Introductory database courses routinely present exactly these benefits as motivations for adopting DBMS technology over file systems.
Why Other Options Are Wrong: Any single item selected as “not a disadvantage” would be incomplete; the statement “All of the above are advantages” captures the full truth.
Common Pitfalls: Confusing “redundancy reduction” with “no redundancy at all.” While databases strive to minimize redundancy, some controlled redundancy may exist for performance or historical reasons.
Final Answer: All of the above are advantages
