1
00:00:00,230 --> 00:00:00,560
Okay.

2
00:00:00,560 --> 00:00:07,010
And once we have our Atlas account in place, let's quickly discuss what is Mongos and where we're going

3
00:00:07,010 --> 00:00:08,900
to use it in this project.

4
00:00:09,140 --> 00:00:16,670
You see, technically we can interact with our database, with our MongoDB database directly, meaning

5
00:00:16,670 --> 00:00:21,860
we can install the driver, essentially a library and just follow the docs.

6
00:00:22,040 --> 00:00:31,310
But a more common approach is to use Mongos, which is an object data modeling library, since it provides

7
00:00:31,310 --> 00:00:38,030
more straightforward and I should say more elegant way to interact with MongoDB.

8
00:00:38,510 --> 00:00:48,320
So yes, essentially Mongos is another layer of abstraction on top of the MongoDB and effectively it

9
00:00:48,320 --> 00:00:56,660
significantly simplifies the process of defining data schemas, validating data and performing Crud

10
00:00:56,690 --> 00:00:57,800
operations.

11
00:00:58,100 --> 00:01:04,230
If you want to install mongos in your own project, the command you're looking for is NPM install.

12
00:01:04,260 --> 00:01:05,230
Mongos.
