Why ORM simplifies database access in Flask - Quick Recap

Recall & Review

beginner

What does ORM stand for and what is its main purpose?

ORM stands for Object-Relational Mapping. Its main purpose is to let developers work with databases using simple code objects instead of writing complex SQL queries.

How does ORM help avoid writing raw SQL in Flask applications?

ORM lets you use Python classes and methods to create, read, update, and delete data. This means you don't have to write SQL commands manually, making code easier and less error-prone.

Explain how ORM improves code readability and maintenance.

ORM uses clear Python code that looks like working with normal objects. This makes the code easier to read and maintain compared to mixing SQL strings inside your code.

What is one way ORM handles differences between database systems?

ORM abstracts the database details so you can switch databases (like SQLite to PostgreSQL) without changing much code. It translates your Python commands into the right SQL for each database.

Why is ORM considered safer when dealing with user input?

ORM helps prevent SQL injection attacks by automatically handling user input safely. It builds queries in a way that avoids dangerous code execution.

What is the main benefit of using ORM in Flask?

A Make the website load faster

B Write database queries using Python objects instead of SQL

C Automatically create HTML pages

D Replace Flask routing system

ORM lets you interact with the database using Python objects, avoiding manual SQL.

How does ORM improve code safety?

A By preventing SQL injection attacks

B By speeding up the server

C By encrypting all data automatically

D By disabling user input

ORM safely handles user input to avoid SQL injection vulnerabilities.

Which of these is NOT a feature of ORM?

A Automatically translating Python code to SQL

B Allowing switching between different databases easily

C Generating CSS styles for the app

D Making code easier to read and maintain

ORM does not handle CSS or styling; it focuses on database access.

What does ORM map between?

A Flask routes and URLs

B HTML and CSS

C JavaScript and Python

D Python objects and database tables

ORM connects Python objects with database tables to simplify data handling.

Why might a developer choose ORM over raw SQL?

A To write less complex and more readable code

B To avoid using Python

C To make the app run offline

D To create mobile apps

ORM reduces complexity by letting developers use Python code instead of raw SQL.
