3.2. FRAMEWORK

The Developing the "Click and Shop" e-commerce platform involves selecting appropriate technologies and architectural patterns to ensure scalability, maintainability, and performance. Utilizing PHP for server-side scripting and MySQL for database management provides a robust foundation for the application.

1)    Technology Stack

·        Backend: PHP, a widely used open-source scripting language, is employed for server-side development.

·        Frontend: HTML, CSS, and JavaScript are used to create responsive and interactive user interfaces.

·        Database: MySQL serves as the relational database management system, handling data storage and retrieval efficiently.

·        Web Server: Apache or Nginx is configured to serve the application and manage HTTP requests.

2)    Architectural Pattern

The application adopts the Model-View-Controller (MVC) architectural pattern, which separates the application logic into three interconnected components:

·        Model: Manages the data and business logic.

·        View: Handles the presentation layer and user interface.

·        Controller: Processes user input and interacts with the Model and View components.

This separation enhances code organization, reusability, and scalability.

3)    PHP Framework Selection

To streamline development and incorporate best practices, a PHP framework is selected. Among the popular choices are:

·        Laravel: Known for its elegant syntax, extensive documentation, and a rich set of features, Laravel is a preferred choice for e-commerce applications. It offers built-in tools for routing, authentication, and database management.

·        Symfony: A flexible and scalable framework, Symfony is suitable for complex and high-performance applications. It provides reusable components and a robust architecture.

·        CodeIgniter: Lightweight and easy to learn, CodeIgniter is ideal for developers seeking a simple yet powerful framework. It offers a small footprint and straightforward configuration.

For "Click and Shop," Laravel is chosen due to its comprehensive ecosystem, active community support, and suitability for e-commerce development.

4)    Database Design

A well-structured database schema is crucial for efficient data management. The design includes the following key tables:

·        Users: Stores user information, including credentials and contact details.

·        Products: Contains product details such as name, description, price, and stock quantity.

·        Orders: Records order information, including user ID, order date, and status.

·        Order Items: Captures the relationship between orders and products, detailing quantities and prices.

·        Payments: Manages payment transactions, including payment method and status.

This relational design ensures data integrity and facilitates efficient queries.

5)    Security Measures

Implementing robust security practices is essential:

·        Input Validation and Sanitization: Prevent SQL injection and cross-site scripting (XSS) attacks.

·        Password Hashing: Use secure hashing algorithms (e.g., bcrypt) for storing passwords.

·        HTTPS Protocol: Ensure data transmission is encrypted.

·        Session Management: Implement secure session handling to protect user data.

6)    Deployment and Maintenance

Post-development, the application is deployed to a production environment:

·        Hosting: Choose a reliable hosting provider supporting PHP and MySQL.

·        Version Control: Utilize Git for code management and collaboration.
