00:00:00,430 --> 00:00:06,010
All right, so database models, this is something we've seen come back again and again.
2
00:00:06,850 --> 00:00:13,510
And in essence, a data base model is nothing more than a way to organize and store your data, but
3
00:00:13,510 --> 00:00:15,340
it also does so much more than that.
4
00:00:15,910 --> 00:00:20,520
That core definition explains only a portion of what's going on here.
5
00:00:20,530 --> 00:00:23,350
And there are many, many database models out there.
6
00:00:24,340 --> 00:00:32,050
To list some here, you have hierarchical networking entity, relationship, relational, object oriented,
7
00:00:32,050 --> 00:00:35,480
flat, semi structured, et cetera, et cetera.
8
00:00:35,710 --> 00:00:38,020
There are many, many models out there that you can use.
9
00:00:38,680 --> 00:00:48,070
And a lot of these models are designed with rules and concepts in place that allow you to create a view
10
00:00:48,070 --> 00:00:49,820
of the data that you're going to store.
11
00:00:50,350 --> 00:00:55,570
Now, the one that we will be looking most at throughout the course is relational because it is still
12
00:00:55,570 --> 00:01:00,100
to this day one of the most popular and widely used models out there.
13
00:01:00,550 --> 00:01:07,150
But I selected two other models that I thought were very important to look at their slightly outdated
14
00:01:07,150 --> 00:01:10,360
and they were popular way back in the 70s and 80s.
15
00:01:10,960 --> 00:01:15,780
But they hold a core foundation of where we started to where we are now.
16
00:01:16,180 --> 00:01:19,320
So we'll be taking a closer look at hierarchical and networking.
17
00:01:19,780 --> 00:01:20,680
Let's get into it.
