Python And SQLAlchemy ORM | SQLAlchemy Basics | Working With Python Databases
no canal de: PyLounge - программирование на Python и всё о IT
In one of the previous videos, we discussed how to work with various databases, in particular with MySQL via Python. And at the end of that video, I mentioned one interesting thing that makes life much easier for a programmer working with a database. This thing is ORM. ORM (Object-Relational Mapping) is a technology that allows you to connect databases with objects in the programming language. That is, we can create a database and work with it directly in Python, without using SQL queries directly. For Python, there are popular Django ORM, which is used in Django to work with models, Peewee ORM, PonyORM and many others. But today we will talk about, perhaps, the most popular, powerful and recognized by developers Python ORM - SQLAlchemy.
