Object-Oriented Architecture

The project uses a reusable CRUD class built on PDO.

The main entities extend the shared database functionality while providing methods specific to their responsibilities.

CRUD

├── Project
├── User
├── Category
├── Reward
├── Pledge
└── Comment

This architecture keeps database operations reusable while separating the logic of each entity.

Purpose

Crowdfund was created to explore the architecture behind crowdfunding platforms while applying object-oriented PHP, relational database design, CRUD operations and reusable backend components.

The project focuses on building a complete and functional web application where multiple entities interact through meaningful database relationships.

Future Improvements

Potential future improvements include payment processing, richer campaign media management, creator analytics, campaign updates and notification systems.
