Hello again.
Welcome to the next section.
So first of all, hopefully you can see me.
I am wearing camouflage.
I know that can make it a little challenging, but I am here.
Not just a floating head.
With that said, this section is.
Well, I keep saying important.
Everything is important, but this section is really taking us back to basics.
In a way.
We're talking about data types.
So if you remember way back, I don't know, Section three ish, I mentioned that we would come back
to data types when I introduced VAR chart of our car, however you want to say it.
And integers are two data types we've been working with, which are great.
They're very useful, but there is a big world outside of those.
What about things like decimals?
How do we store currency price information where we have information after the decimal?
How do we store things like dates and time?
Well, make word my watch go things like dates and times.
There's a lot of information that we need to store that doesn't neatly fit into our chart or integers.
So this section is all about introducing and surveying those kind of different data types.
And I could have done this early on in the course, but I've done it in the past like that in person.
And I find that students get too bogged down just worrying about all the data types when really they
need to be focusing on things like create tables and insert statements.
That's the focus of SQL.
In my SQL, we can insert or we can add new data types easily.
So that's what this section is.
We have the two we've been working with.
Now we're adding a bunch more, a ton of exercises here, nothing complex with our data.
We're not using any brand new data set.
All we're going to focus on are the data types we'll see.
In particular, we'll focus on dates, times, date times, timestamps, all this terminology.
It gets a little crazy, but hopefully we can simplify that in this section.
All right.
See in the next video.
