Dashboard Data Flow

dashboard.html → dash1.php → get_balance.php + get_transactions.php → Portfolio Summary Display

🗄 Database Integration

Core Tables

Based on the PHP files, the system uses these main database tables:

1. Users Table - Managed by login.php, registration.php
2. Transactions Table - Updated by individual *_transaction.php files
3. Stock Holdings - Tracked by get_owned_stocks_*.php files

Data Consistency

• Each company has separate transaction handlers ensuring data integrity
• Balance updates are handled through get_balance.php
• Transaction history is maintained via his.php and stock-history.php

🚀 Development Workflow

Frontend Development

1. HTML pages for user interface
2. Company-specific pages for each stock
3. Responsive design with integrated styling

Backend Development

1. PHP files handle all server-side logic
2. Individual handlers for each company's transactions
3. Separate API endpoints for data retrieval

Full-Stack Integration

1. Node.js for modern JavaScript features
2. PHP for database operations and business logic
3. MySQL for data persistence

📝 File Naming Conventions

HTML Files

• PascalCase: Homepage.html, Average.html
• Lowercase: main.html, news.html, feedback.html

PHP Files

• Lowercase with underscores: amazon_transaction.php
• Action-based: get_balance.php, get_transactions.php

Image Files

• Lowercase company names: amazon.png, apple.png
• Descriptive names: Bull-removebg-preview.png

This structure demonstrates a well-organized, scalable architecture that separates concerns between frontend presentation, backend logic, and data management while maintaining individual handlers for each company's stock operations.
