1
00:00:02,200 --> 00:00:04,900
Now, we did explore SQL.

2
00:00:04,900 --> 00:00:07,050
In this course section, we're going

3
00:00:07,050 --> 00:00:09,600
to dive into NoSQL databases.

4
00:00:09,600 --> 00:00:12,020
And, of course, a couple of sections ago,

5
00:00:12,020 --> 00:00:16,740
I already gave you a first comparison of these two systems.

6
00:00:16,740 --> 00:00:18,450
So, definitely make sure you have a look

7
00:00:18,450 --> 00:00:21,510
at that section again, where I introduce you

8
00:00:21,510 --> 00:00:23,930
to databases in general, in order

9
00:00:23,930 --> 00:00:27,090
to understand why we have SQL and NoSQL,

10
00:00:27,090 --> 00:00:30,220
and what the general differences are.

11
00:00:30,220 --> 00:00:32,630
In this course section, we are, of course,

12
00:00:32,630 --> 00:00:37,630
going to have a closer look at how NoSQL databases work,

13
00:00:38,620 --> 00:00:42,280
what the idea is, and which databases we have there,

14
00:00:42,280 --> 00:00:44,560
which databases we can install.

15
00:00:44,560 --> 00:00:47,920
And we're then going to install MongoDB,

16
00:00:47,920 --> 00:00:52,370
a very popular and common NoSQL database system.

17
00:00:52,370 --> 00:00:54,930
And we'll see how we can install that and set it up

18
00:00:54,930 --> 00:00:57,380
and how we can then, most importantly,

19
00:00:57,380 --> 00:01:00,040
use it for running CRUD operations.

20
00:01:00,040 --> 00:01:02,410
So, for inserting data, storing data,

21
00:01:02,410 --> 00:01:04,790
updating and deleting data and, of course,

22
00:01:04,790 --> 00:01:08,360
also fetching data with different queries.

23
00:01:08,360 --> 00:01:12,010
So, basically, what we also did with SQL,

24
00:01:12,010 --> 00:01:14,620
but now with NoSQL and, therefore,

25
00:01:14,620 --> 00:01:16,950
quite different, as you will see.

26
00:01:16,950 --> 00:01:19,600
My strong recommendation is that you do complete

27
00:01:19,600 --> 00:01:21,880
the SQL sections first, before you dive

28
00:01:21,880 --> 00:01:24,230
into this one here, so that you, thereafter,

29
00:01:24,230 --> 00:01:27,840
really have a good understanding of which different systems

30
00:01:27,840 --> 00:01:31,883
we have, and why we have them, and how they work and differ.
