Hello again.

00:01.050 --> 00:02.730
Welcome to the next section.

00:02.730 --> 00:05.080
So first of all hopefully you can see me.

00:05.130 --> 00:06.450
I am wearing camouflage.

00:06.660 --> 00:11.530
I know that I can make it a little challenging but I am here not just a floating head.

00:11.550 --> 00:17.730
With that said this section is a well keep saying important everything is important but this section

00:17.730 --> 00:22.340
is really taking us back to basics in a way we're talking about data types.

00:22.440 --> 00:26.110
So if you remember way back I don't know Section 3 ish.

00:26.280 --> 00:29.050
I mentioned that we would come back to data types.

00:29.160 --> 00:35.460
When I introduced Vardar of our car I forgot to say it and integers are two data types you've been working

00:35.460 --> 00:36.550
with which are great.

00:36.570 --> 00:40.310
They're very useful but there's a big world outside of those.

00:40.320 --> 00:42.690
What about things like decimals.

00:42.690 --> 00:48.020
How do we store currency you know price information where we have information after the decimal.

00:48.270 --> 00:52.550
How do we store things like dates and time.

00:52.590 --> 00:57.050
Well we're going to go things like dates and times.

00:57.330 --> 01:03.270
There's a lot of information that we need to store that doesn't neatly fit into Vardar or integers.

01:03.300 --> 01:09.210
So this section is all about introducing and surveying those kind of different data types and it could

01:09.210 --> 01:14.640
have done this early on in the course but I've done it in the past like that in person and I find that

01:14.640 --> 01:20.070
students get too bogged down just worrying about all the data types when really they need to be focusing

01:20.070 --> 01:22.900
on things like create tables and insert statements.

01:22.950 --> 01:25.140
You know that's the focus of sequel in my essay.

01:25.140 --> 01:28.950
Q Well we can insert or we can add new data types easily.

01:28.980 --> 01:30.320
So that's what this section is.

01:30.420 --> 01:31.890
We have the two we've been working with.

01:31.890 --> 01:35.610
Now we're adding a bunch more a ton of exercises here.

01:35.610 --> 01:37.620
Nothing you know complex with our data.

01:37.680 --> 01:40.810
We're not you know using any brand new data set.

01:40.920 --> 01:42.990
All we're going to focus on are the data types.

01:43.050 --> 01:43.640
We'll see.

01:43.650 --> 01:47.590
In particular we'll focus on dates times date times time stamps.

01:47.760 --> 01:53.220
All of this terminology it gets a little crazy but hopefully we can simplify that in this section.

01:53.220 --> 01:54.230
All right.

01:54.280 --> 01:55.620
See in the next video.
