Study Notes
Interactive System Development
- Interactive system development uses a modular approach for program development
- The core computation and interface parts are developed separately and combined
- User Interface (UI) toolkits are used for the interface portion
- Model-View-Controller (MVC) framework is an example of this modular approach
- MVC divides the software application into three interconnected parts: model, view, and controller
- Model: Defines the data structure and processes (e.g., logic for banking application)
- View: Presents the data formatted for the user (e.g., displays account balance)
- Controller: Handles user input and interacts with the model & view (e.g., processes deposit/withdraw requests)
MVC Framework Components
- Model: Defines the logical data structure and high-level classes of the application
- View: Contains the user interface logic, presenting the model in a user-friendly way
- Controller: Acts as an intermediary between the model and view; handles user input and data manipulation
MVC Example (Banking Application)
- Model: Manages account balance, interest calculations, and transfers
- View: Displays account transactions, balances, etc.
- Controller: Processes user input (deposit, withdraw), updates the model, and updates the view
Advantages of MVC
- Faster development due to parallel development of components
- Multiple views can be created for a single model
- Changes to one component don't affect others
- SEO-friendly URLs can be created easily
- Supports test-driven development
Disadvantages of MVC
- Inefficient data access in the view due to minimal code duplication
- Difficulty implementing MVC with modern interfaces
- Programmers need knowledge of the application's business processes
MVC Implementation Steps
- Browser requests the MVC application
- Controller processes the request
- Controller uses the data model of the application
- Result is sent to the appropriate view
- View processes the data and formats it for presentation
MVC Implementation (Bank Application)
- Model stores account balances
- Users interact with the controller to make deposits or withdrawals
- Controller updates balances in the model; view updates the displayed balances
