What are Django queries and how do they work?

Django queries are used to retrieve data from the database using Django's ORM. They allow you to filter, sort, and manipulate data easily.

Can you give me an example of a simple query?

Sure! A simple query to get all objects from a model called 'Book' would be: Book.objects.all().

How do I filter results in a query?

You can filter results using the filter() method. For example: Book.objects.filter(author='John Doe') retrieves all books by John Doe.

What about ordering the results?

You can order results using the order_by() method. For instance: Book.objects.all().order_by('title') orders books by their title.
