00:00:00,550 --> 00:00:03,890
The MVC model may sound
like a lot of work, but

2
00:00:03,890 --> 00:00:06,900
it provides many,
many benefits for developers.

3
00:00:08,228 --> 00:00:09,850
Most importantly,

4
00:00:09,850 --> 00:00:15,780
MVC separates a program into individual
parts that handle specific tasks.

5
00:00:15,780 --> 00:00:17,860
The model only handles data.

6
00:00:17,860 --> 00:00:21,990
The view only handles the presentation
of data, and the controller handles

7
00:00:21,990 --> 00:00:26,800
all of the communication between
the model, view, and user.

8
00:00:26,800 --> 00:00:31,280
This one principal task is sometimes
called the separation of concerns,

9
00:00:31,280 --> 00:00:35,460
meaning each part of the program
has just a single task or concern.

10
00:00:36,730 --> 00:00:40,890
This pattern let's team of developers
work on different parts of a program

11
00:00:40,890 --> 00:00:44,065
at the same time leading
to faster development.

12
00:00:44,065 --> 00:00:48,990
MVC also makes it easier to
find errors if one part isn't

13
00:00:48,990 --> 00:00:53,530
returning what you're expecting, then
it's much easier to fix because you only

14
00:00:53,530 --> 00:00:58,200
need to look into one specific part or
concern to locate the error.

15
00:00:59,200 --> 00:01:03,020
MVC helps you create flexible and
reusable components.

16
00:01:03,020 --> 00:01:07,123
For example,
if the model only contains specific data,

17
00:01:07,123 --> 00:01:12,607
you can use the same model with different
views using the same information.

18
00:01:12,607 --> 00:01:16,908
That is to say, a database like
IMDB can use the same data for

19
00:01:16,908 --> 00:01:21,726
a movie but presented on different
pages such as the trailer page,

20
00:01:21,726 --> 00:01:24,235
a ratings page or on the homepage.

21
00:01:25,325 --> 00:01:30,105
Overall, MVC provides a pattern for
you to program in a very structured and

22
00:01:30,105 --> 00:01:34,115
efficient way that helps you work
faster and create better software.

23
00:01:35,270 --> 00:01:37,600
Let's dig deeper into the MVC pattern.

24
00:01:37,600 --> 00:01:41,590
In the next video, I'll introduce you
to the master mind behind the pattern.

25
00:01:41,590 --> 00:01:44,490
The C in MVC, known as the controller.

26
00:01:44,490 --> 00:01:45,050
See you there.
