It's good that we learned about SQL
and MySQL, specifically in the theory,
and that we had a thorough look at how it works
and how the query language looks like and is used,
but of course, this is a course that wants
to turn you into a web developer.
Therefore you need to be able to apply
what you learned about SQL in a website
that you are building.
So on the backend into NodeJS code of a website,
you are building, for example.
And therefore in this course section, we're going to explore
how you can use your newly gained SQL knowledge
and run those SQL query commands
from inside your website backend code.
So that you can build a website
that interacts with a database.
And for that in this course section,
we're going to build a demo project, a little blog,
and you're going to learn how you can connect
to databases from inside your code
so that you don't rely on MySQL workbench only,
but that instead you can run queries from inside your code,
which of course is what you need to do in order to interact
with a database from inside your code.
And we will have a look at
how we can perform CRUD operations from inside our code.
So how we can create, read, update,
and delete items from a database.
And last but not least in this course section,
we are, of course, also going to see
how we can fetch data from a database
and then output that data in our templates.
So how we can bring it onto the screen of our visitors.
