Stored Procedures — Advantages for Integrity and Architecture Which of the following is a valid advantage of using stored procedures across multiple applications?

Introduction:
Stored procedures centralize business rules and data manipulation logic inside the DBMS. They are often reused by many applications, which improves consistency, security, and performance. This question asks you to identify a genuine advantage among several distractors.

Given Data / Assumptions:

• Stored procedures can be parameterized and permissioned.
• Execution plans are typically cached by the DBMS.
• Reusing the same code path promotes consistent validations and side effects.

Concept / Approach:
The key benefit is standardized, centralized logic: validations, constraints, and transformations live in one place. That improves data integrity compared to duplicating logic across many client apps. Procedures may also reduce network traffic by sending parameters instead of large ad-hoc SQL strings and can enhance security by limiting direct table access.

Step-by-Step Solution:
1) Compare each option against known stored procedure benefits.2) Identify the option that increases integrity through reuse and central control.3) Eliminate options that contradict typical benefits (for example, increased network traffic).

Verification / Alternative check:
Operational patterns show organizations standardize complex updates in procedures to avoid drift and inconsistencies across many applications and services.

Why Other Options Are Wrong:

• Longer to write than VB: Effort depends on context; not a general truth or advantage.
• Network traffic increases: Usually decreases; only parameters are sent.
• Thicker clients: Centralizing logic in the DB often thins clients.
• Cannot be compiled/cached: DBMSs cache execution plans for procedures.

Common Pitfalls:
Duplicating logic in many applications causes divergence and integrity issues; stored procedures mitigate this risk.

Final Answer:
Data integrity improves as multiple applications reuse the same vetted stored procedure.
