-: Hey, what's up, Gurus?
Welcome to section 7, the "Data Serving Layer".
For reference, you are right here.
So we're a little past the halfway point,
heading into that last third of the course.
Congratulations, keep it up.
Keep moving.
In this section,
we are going to talk about first, a foundation.
Talk a little bit about schema and dimensions
and what that is.
We're going to talk about designing
and building external tables.
And we're going to talk about metastores and metadata.
Now, for this section,
some of this should be a refresher,
especially when we talk about some basic concepts,
such as schema and dimensions.
If it's not and you're wildly confused,
you might want to jump back in
and do a little bit more research
into some of those basic topics.
However, you should be good to move forward.
You certainly don't need to be an expert
and we will cover the basics
of what you need to know.
Second, don't forget the services.
So as we move through the course,
keep in mind that you want to be thinking
about the Azure services
that use the key concepts that we are talking about.
And then we'll be using some very light code.
This is really more a focus on concepts.
So I'm not going to dive a whole lot into SQL
and other things as it's likely not going
to be on the DP-203.
So we'll try and keep focus on the DP-203
and keep you moving forward.
With that, hey, let's jump in to section 7.
