MVC Architecture has implemented by Trygve Reenskaug at 1979 for the
first time. It was implemented on Smalltalk at Xerox labs. Then benefits
and advantages of this architecture has been accepted by most of the
coders and software engineers.
It was an information about MVC’s history above. Now lets talk about
what really MVC is. What do you understand from MVC. The word M stands
for Model, V stands for View and C stands for Controller. I am going to
mention about each item.
Model:
It handles data processing and database works part. Model processes events sent by controller. After processing these events then it sends processed data to controller (thus, controller may reprocess it) or directly to view side.

View:
View prepares an interface to show to the user. Controller or model tells view what to show to the user. Also view handles requests from user and informs controller.

Controller:
Let’s say controller is like brain of the system. That is right. Because it processes every request, prepares other parts of the system like model and view. Then the system determines what to do by controller’s commands.

Even if you are junior developer you probably faced with a problem
called “Complexity of Project”. There MVC comes. MVC helps you to
decrease complexity of project. For instance, there is a team with 5
people. If they are working on same project after sometime project
reaches a point which no one cannot understand what is project going to
be. What i mean is MVC splits project to (by default) three different
parts. Like Model, View, Controller.You can say;
As you see above if you split your project three part like
Application Development, Database and Data processing and Interface
development then of course you project will be more understandable and
developers can work more efficiently.
What are the advantages of MVC?
MVC is perfect for team work. As i mention before this architecture splits your project into some parts so, team members can work and their parts without any dependency. Then you will realize that MVC makes your project more systematic.
It is really easy to edit or change some part of your project that makes less development cost and maintenance cost.

MVC doesn’t repeats itself. If you wrote some script for your project.
Because of non-dependancy property of MVC then you may use this script
for another project of yours. And of course it helps you to finish your
project by spending less time then others.
Why MVC is non-standard?
Still waits for developers to discover itself. I know some developers who think that they have to write even every semicolon, letter. you don’t have to do that. However, MVC tries to help you to don’t repeat yourself.
Why MVC is too important for Companies?
Well it is not!. Yes that is true. A company only looks for if a project is done on time or not. Most of the companies doesn’t interested what structure you are using while developing.

Well it is not!. Yes that is true. A company only looks for if a project is done on time or not. Most of the companies doesn’t interested what structure you are using while developing.
Probably you know this formula : P=W/T (P:Power – W:Work – T:Time) As
you see here if you descrease the time so you may done with more Work.
That means money! So, you see how MVC helps you.
Example:
As an example you can think like eyes of a human stands for view, brain stands for controller and neutral system of a body stands for model. You can imagine like when a person sees his friend eyes (view) tells this to the brain (controller). Brain wants to show smile to his friend. To make it possible brain tells your face’s neutral network that make the face smile. Then his face smiles Hope it helped.
