Why stored procedures centralize logic in MySQL - Quick Recap

Recall & Review

beginner

What is a stored procedure in a database?

A stored procedure is a set of SQL statements saved in the database that can be executed as a single unit. It helps perform tasks repeatedly without rewriting the code.

How do stored procedures help centralize business logic?

Stored procedures keep business rules in one place inside the database, so all applications use the same logic, reducing errors and making updates easier.

Why is centralizing logic with stored procedures better than duplicating code in multiple applications?

Centralizing logic avoids repeating code in many places, which lowers mistakes and saves time when changing rules because you update only one place.

What is one performance benefit of using stored procedures?

Stored procedures run inside the database server, so they can execute faster than sending many separate SQL commands from an application.

intermediate

Can stored procedures improve security? How?

Yes, stored procedures can restrict direct access to tables and allow users to run only approved operations, protecting data from unauthorized changes.

What does centralizing logic in stored procedures help prevent?

A Faster network speed

B Code duplication across applications

C More database tables

D Increased disk space usage

Centralizing logic in stored procedures prevents code duplication by keeping business rules in one place.

Where do stored procedures run?

A In the web browser

B On the user's computer

C On the database server

D On a separate application server

Stored procedures run on the database server, which can improve performance.

How do stored procedures improve security?

A By restricting operations to approved procedures

B By allowing direct table access

C By encrypting all data automatically

D By increasing user permissions

Stored procedures improve security by restricting users to run only approved operations.

What is a key maintenance advantage of using stored procedures?

A You increase network traffic

B You need to update logic in every application

C You avoid using SQL

D You can update logic in one place

Updating logic in one place makes maintenance easier and reduces errors.

Which of the following is NOT a benefit of stored procedures?

A Automatically backing up data

B Improving query performance

C Enhancing security controls

D Centralizing business logic

Stored procedures do not automatically back up data; backups are handled separately.
