Introduction of MVC in AJS
- MVC stands for Model View Controller.
- It is still used today in web development.
Definition of MVC in AJS
- MVC is an industry-standard software design pattern for developing web and desktop applications.
- AngularJS is an MVC-based framework for front-end web application development.
- MVC is a fundamental design paradigm of AngularJS that helps structure and organize code more effectively.
Characteristics of MVC in AJS
- MVC is a popular framework for web development because it isolates the application logic from the user interface layer and supports the separation of concerns.
- MVC helps keep code organized, modular, and easier to manage.
- MVC provides a logical structure for organizing code, which makes it easier to maintain, update and extend applications.
The Architecture of MVC in AJS
- A Model View Controller pattern is made up of the following three parts:−
-
View
-
-
-
- It is at the top is the Presentation Layer, which uses web technologies such as HTML, CSS, and JavaScript to offer an intuitive and interactive user interface for users.
- This layer is responsible for capturing user input and displaying system data efficiently.
- This layer contains/represents the user interface (UI) codes/parts of the application.
- It is the middle level of the MVC pattern responsible for displaying all or a portion of the data/user interface to the user.
- It displays data to the user and sends user actions (like button clicks) to the controller.
-
-
- Controller
- This layer acts as a middleman between the Model and the View.
-
It is considered as the top level of the MVC pattern which includes software codes that control or regulate the interactions between the Model and View.
- This layer lies in the Business Logic or Application Layer.
- They primarily/normally use script-based template systems such as JSP, ASP, Node JS, and PHP, and very easy to integrate with AJAX technology.
- This layer acts as the core engine of the system—it processes requests, applies validation rules, executes business operations, and orchestrates communication between the user interface and the database.
- The controller part of codes responds to user input and performs interactions on the data model objects.
- It receives user input from the View, processes it (sometimes using the Model), and returns the result to the View.
- It mainly includes the processing codes using certain back-end languages.
-
Model
-
It is the bottom level of the MVC pattern responsible for maintaining data in databases usually.
-
This level is in the Data Layer, managed by different types of Databases. This database component is tasked with securely storing, retrieving, and managing all records, and related metadata.
- This layer represents the data and business logic of the application.
- It interacts with the database and handles data-related operations (like fetching, updating, deleting, etc.).
-
- Controller
