Doctrine ORM, or Object-Relational Mapping, is like a translator between two languages. Imagine you only speak in objects, and your database only understands tables. Doctrine ORM is the tool that connects your object-oriented code with your relational database.
For example, let’s say you have a User class in your application. With Doctrine, you don’t need to manually create a SQL table to store that user’s information. Doctrine takes care of everything. It takes your User class, understands how it should be represented in the database, and automatically manages the creation and updating of records.
In short, Doctrine simplifies working with databases by allowing you to focus on your code while it handles the transformation into SQL queries for you.
