MVC, MVP & MVVM all this are a project design patterns which are very useful for developer to structure the project & write code that can be easily understandable, maintainable, extensible add need features and tested. All the 3 design pattern share some similarities, and there are difference between MVC MCP & MVVM. In the article post, let’s explore the MVC, MVP & MVVM design patterns. In order to choose the perfect pattern for your upcoming project’s let’s discuss the difference between them.
Model View Controller (MVC)
A Model View Controller (MVC) is a software architectural design pattern mostly used for user Interface (UI design). It separate the project into three parts i.e. Model View Controller, It is a way how to information is presented in front of user or how the data is accepted from user from user event’s.
Model represent a data structure layer of an application (database)
- the model, which represents the data;
- the view, which displays the data;
- the controller, which handles user input.
The Model View Controller (MVC) is a software architectural pattern for implementing user interfaces. It divides a given software application into three interconnected parts, so as to separate internal representations of information from the way information is presented to or accepted from the user.
Here Controller stores data to the model & tell the view this data is been updated .
View fetch the data/updated data from models and display it in view.
Model View Presenter (MVP)
The Model View Presenter is originated from MVC pattern to fix some short comes of MVC software development architecture.
Here Presenter role is similar to controller it handles all the input from user and update the view immediately if required. Presenter keep observing the UI events happens in Views, Write/store the data into model, then read back data from model & provide the updated data to View to display it users.
MVP pattern can be used with any type of application, Best to be used in event-driven applications like Rich Internet Application (RIA’s).
Model-View-ViewModel (MVVM architecture)
Recently MVVM is been added into the architecture pattern of software development world. Here View Model Play an important role in the MVVM architecture pattern, It managed the communication between View and Model, This make MVVM application to be built easily and tested then any other pattern.
MVC, MVP, and MVVM are most commonly used software design architecture patterns. They have their own strength & weaknesses respectively.
Here View knows all about ViewModel, View Model know about model and Model knows nothing.
View Model Perform perform it’s logics and store the data into model, and it also observe the data changes in model immediately update itself for the changed.
MVVM is a more recent addition to the world of software architecture patterns. It builds on MVP by adding a fourth component: the view model. The view model manages communication between the view and the model, providing a clean separation of concerns. This makes MVVM applications easier to develop and test than those using other patterns.
What Application design pattern best for project
MVC, MVP & MVVM each of the has it own advantages & disadvantages and will differ project to project.
I have Personally worked on all three design patterns, MVC & MVP create lots of messy in the architecture.
MVVM design pattern is better then MCV/MVP because MVVM uses unidirectional data & dependencies flow.
