Django ORM Deep Dive - Introduction to Databases & SQL
Показать описание
In this video, we'll introduce relational databases, and will cover important foundational topics such as the anatomy of a database (tables, rows, columns), data types, and primary keys and foreign keys.
We'll also look at how to use SQL to query a database to find records in tables, and to do more complex operations such as aggregating data, grouping data, and joining tables with SQL joins.
This video serves as an introduction to a wider course on the Django ORM and database tools.
