In a dynamic world you cannot have an application that is not flexible. In fact today an ideal web application is the one that can be easily extended or scaled to accommodate changing requirements. An application may only need standard features today but tomorrow it may need extensions and customizations. What to do then? Do you re-develop the whole application?
To work around a situation like this Radix uses ASP.Net MVC framework to develop applications where every component can be extended or customized later on. We are using ASP.Net MVC to develop or revise existing websites.
So what is MVC? MVC is an architecture pattern that separates business logic from user interface for a web browser. MVC comprises of 3 main divisions.
Model – Contains business or domain logic along with data structure
View – Contains layout and presentation of data
Controller – Handles end user requests and responds to them
These three components together manage input, business logic, and output of an application. Radix uses MVC framework to develop interactive web applications and desktop applications.
Model represents and manages domain logic of an application. We work with domain model that contains business domain data. It responds to requests from View and instructions from Controller to update business logic. The core functionality of domain model is to maintain application domain behavior and data. We also offer View Models that represent data transferred between View and Controller.
View represents user interface in web based applications. It displays buttons, design elements, graphics, forms, information, textual output, etc. of application. This comprises of HTML layout only.
Controller manages user interaction. Considered to be the brain of an application, Controller processes and responds to requests, inputs and interactions. It processes requests, gets the appropriate data, and identifies appropriate view to represent it to end user. It acts as a link between the system and its users.
We use MVC to develop applications that can be easily managed with changing requirements. We use MVC patterns to separate user interface from substance of an application.
Why MVC Development with Radix?
MVC based application development has become a core development strategy at Radix. We are using MVC architecture to improve code reusability and identify issues as belonging to a specific domain and solve them in a more effective manner.
1) Separate Development: We use MVC to isolate the application code into model (business logic), view (UI logic), and controller (input logic) independently. We build interfaces based on core contracts that can be tested by using mock objects. Mock objects will imitate the behavior of actual object.
2) Easy Code Maintenance: Since we divide the application into three main domains, code maintenance and debugging becomes very easy. We don’t have to run through the entire code. We identify the issue as relating to a specific domain and debug that particular section only. This lowers our efforts and expedites maintenance process.
3) Multiple View Support in UI: Since MVC separates model, view, and control of application from each other, we design user interfaces in such a way that they can display multiple views of the same data at the same time.
4) Improved Application Performance: We use MVC’s web forms instead of HTML based forms in web application. This reduces application loading and processing time giving better performance.
5) Better Application Testing: We test model, view, and control part of the application separately. Isolated testing of these divisions makes it easy for us to identify latent vulnerabilities or issues and solve them.
6) Extensibility: ASP.Net MVC framework has components that are easy to replace or customize. It is easy to plug-in view engine, URL routing policy, action method parameter serialization, and other third party components as per the requirements.
7) Change Management: One thing that changes most frequently in an app is its user interface. Business rules do not change that very often. Since display and interface is kept separate from functionalities it becomes easy to manage design level change. New theme can be implemented, new fonts can be embedded in the design, etc.
MVC Development Practices
Like mentioned earlier the central idea of MVC is to improve code reusability and isolate issues to a particular domain. For this purpose we follow below mentioned guidelines when developing Model, View, & Controller part of the application.
Model is the underlying structure for data that will be used by different parts of an application. This means different parts will seek data from this common structure. So we make sure that we:
- Develop properties to represent specific data.
- Develop business logic to ensure the represented data fulfills design requirement.
View is responsible for displaying required data to end users. There are certain best practices that we follow for View. We develop:
- Separate presentation code to format and render data.
- Common presentation areas and put them in layout view.
- Partial views that are independent of layout and use fragments of presentation code.
Controller binds model and view together and runs them in an application. Controllers are responsible for handling end user requests. They direct traffic to where it needs to go. They figure out which view meets the end user request. So we take extra care when developing controller part of the application. As a practice we:
- Isolate controllers from non-testable or non-flexible applications.
- Isolate controllers from data access or business logic.
- Use Inversion of Control (IoC) container to manage dependencies. This makes testing very easy.
- Use strongly-typed views instead of magic strings.
