Drinks Inventory System - Project Summary

Project Overview

The Drinks Inventory System is a web application designed to manage the inventory of drinks, track stock levels, create orders, and automatically adjust desired stock levels based on consumption patterns. The system will be built using PHP 8.4+, Slim framework, Twig templates, and SQLite database.

Key Documents

This project is documented through several key files:

1. Feature Specifications: Outlines the core features and requirements of the system.
2. Database Schema: Defines the database structure and relationships.
3. Development Guidelines: Provides guidelines for development workflow and standards.
4. Implementation Tasks: Lists all tasks required to implement the system.
5. Directory Structure: Proposes an organized directory structure for the project.
6. Implementation Plan: Outlines a timeline and approach for implementing the system.

Core Features

The system includes four core features:

1. Drink Type Management: Adding, editing, and viewing drink types with desired stock levels.
2. Inventory Management: Updating and viewing current stock levels and history.
3. Order Management: Creating orders based on stock levels and tracking their status.
4. Adaptive Stock Level Adjustment: Automatically adjusting desired stock levels based on consumption patterns.

Technical Architecture

The application follows a layered architecture:

1. Entity Layer: Represents the database tables (DrinkType, InventoryRecord, Order, OrderItem, SystemConfig).
2. Repository Layer: Handles database operations for each entity.
3. Service Layer: Implements business logic and coordinates between repositories.
4. Controller Layer: Handles HTTP requests and responses.
5. View Layer: Twig templates for rendering the UI.

Database Design

The database consists of five tables:

1. DrinkType: Stores information about different types of drinks.
2. InventoryRecord: Stores the history of inventory changes.
3. Order: Stores information about orders.
4. OrderItem: Stores items within an order.
5. SystemConfig: Stores system configuration parameters.

Implementation Approach

The implementation will follow an iterative approach over a 6-week period:

1. Phase 1 (Week 1): Project setup and foundation
2. Phase 2 (Weeks 2-3): Core features implementation
3. Phase 3 (Weeks 4-5): Advanced features and refinement
4. Phase 4 (Week 6): Documentation and deployment

Development Practices

The project will adhere to the following development practices:

1. Object-Oriented Design: Using classes for entities, repositories, services, and controllers.
2. Dependency Injection: Registering services in the container and using dependency injection.
3. Testing: Writing unit and feature tests for all components.
4. Code Quality: Following PSR coding standards and using static analysis tools.
5. Version Control: Using Git for version control.

Next Steps

To begin implementation, follow these steps:

1. Set up the project structure according to the Directory Structure document.
2. Implement the database connection and schema migrations.
3. Create the entity and repository classes.
4. Follow the Implementation Plan for subsequent steps.
