00:00:05,110 --> 00:00:06,340
In this video.

2
00:00:06,340 --> 00:00:10,300
Let's talk about types of databases.

3
00:00:10,390 --> 00:00:16,510
Well, we have many types of databases, but let's focus on these two.

4
00:00:16,900 --> 00:00:21,700
The first one is what we call the relational databases.

5
00:00:21,700 --> 00:00:26,380
And lastly is what we call no obscure database.

6
00:00:26,380 --> 00:00:31,020
And the full meaning of this one simply means not only SQL.

7
00:00:31,030 --> 00:00:35,170
So let's start with the relational database.

8
00:00:35,500 --> 00:00:36,250
All right.

9
00:00:37,210 --> 00:00:45,280
A relational database is a database that stores data in tables with rows and columns.

10
00:00:45,280 --> 00:00:52,490
And this how it stores data in a table format with rows and columns.

11
00:00:52,510 --> 00:00:58,630
An example of this database are my SQL and Oracle.

12
00:00:58,930 --> 00:01:05,830
If you have used relational database before, you can see how is being presented something like this.

13
00:01:06,560 --> 00:01:11,150
So let's take this flow of data as a banking application.

14
00:01:11,330 --> 00:01:20,690
We may have a table that stores all customers and one table that stores all employees and many more.

15
00:01:21,320 --> 00:01:25,650
And we use drawing to relate a table to each other.

16
00:01:25,670 --> 00:01:29,420
But in no square world, it doesn't work in that way.

17
00:01:29,450 --> 00:01:33,170
So what is non relational database?

18
00:01:33,200 --> 00:01:34,520
Let's get going.

19
00:01:34,820 --> 00:01:43,400
No escrow database are non relational database that do not use traditional table based structure of

20
00:01:43,400 --> 00:01:50,330
relational database, but instead it stores data in a JSON documents format.

21
00:01:50,930 --> 00:01:59,270
The differences between relational database and non relational database is the way a stored data in

22
00:01:59,270 --> 00:02:03,110
relational world is stored data in a table format.

23
00:02:03,910 --> 00:02:10,479
And this is how non relational database stores data in a form of JSON.

24
00:02:10,870 --> 00:02:16,770
So if you know JavaScript object working with no SQL database is pretty easy.

25
00:02:16,780 --> 00:02:23,230
And an example of this is called Coach DB, Redis and MongoDB.

26
00:02:23,410 --> 00:02:33,340
So MongoDB falls under non relational database or no SQL database, meaning not only SQL, meaning that

27
00:02:33,340 --> 00:02:40,300
we can use the SQL idea to work with what NoSQL database like MongoDB.

28
00:02:40,630 --> 00:02:47,110
Now that we know the differences between the relational and non relational, we are going to work with

29
00:02:47,110 --> 00:02:50,960
what non relational or no database.

30
00:02:50,980 --> 00:02:54,050
An example is what you call MongoDB.

31
00:02:54,070 --> 00:02:56,590
So let's get into that the next video.
