What is an ORM, and how does it simplify database interactions?

An ORM (Object-Relational Mapper) is a tool that allows developers to interact with a database using object-oriented programming instead of writing raw SQL queries. It maps database tables to Python classes and rows to objects, making database operations more intuitive.

ORMs like Django’s ORM or SQLAlchemy simplify database interactions by abstracting the underlying SQL code. For example, instead of writing a SQL query to fetch data, a developer can use a Python method like Model.objects.all() to retrieve all records from a table.

In full-stack development, ORMs improve productivity and reduce the risk of SQL injection attacks. They also make it easier to switch between different databases, as the ORM handles the differences in SQL dialects. This makes ORMs a valuable tool for backend developers.
