🏗️ System Architecture

The project follows the Model-View-Controller (MVC) architectural pattern provided by Laravel, promoting clean separation of concerns, maintainability, and scalability.

Architecture Overview

• Model – Handles database operations using Eloquent ORM.
• View – Blade templates for rendering the user interface.
• Controller – Manages business logic and coordinates requests between models and views.

Software Engineering Principles

• MVC (Model-View-Controller)
• Eloquent ORM
• Route Model Binding
• Form Request Validation
• Database Transactions
• Role-Based Access Control (RBAC)
• Activity Logging (Audit Trail)
• Server-side Business Logic
• Responsive Bootstrap User Interface

Business Rules Implemented

• Automatic stock increase after purchase transactions.
• Automatic stock deduction after sales transactions.
• Stock validation prevents negative inventory.
• Historical selling prices are stored with every sales transaction.
• Line totals are calculated on the server.
• Deleted purchase transactions automatically restore stock.
• Deleted sales transactions automatically restore stock.
• User permissions are enforced through Role-Based Access Control (RBAC).
• Critical business operations are protected using database transactions.

Project Goal

The primary objective of this project is to demonstrate the implementation of a production-style Inventory Management System using Laravel while applying software engineering best practices, secure business logic, and maintainable application architecture.
