terra-stock System Requirements Document

Introduction

The purpose of this document is to outline the system requirements for the "terra-stock" project, a stock management application designed for small retailers. This document will provide a comprehensive overview of the system, detailing functional requirements, user personas, core user flows, and other essential components to guide the development process.

System Overview

The "terra-stock" application is intended to assist small retailers in managing their inventory efficiently. The system will enable users to track stock levels, manage product information, and streamline the ordering process. The application will be designed with user-friendly interfaces and functionalities tailored to the needs of small retail businesses.

Functional Requirements

• As a Retailer, I should be able to add new products to the inventory.
• As a Retailer, I should be able to update product details such as price, description, and stock levels.
• As a Retailer, I should be able to remove products from the inventory.
• As a Retailer, I should be able to view current stock levels for all products.
• As a Retailer, I should be able to receive notifications when stock levels are low.
• As a Retailer, I should be able to generate reports on sales and inventory levels.
• As a Retailer, I should be able to manage supplier information and reorder stock.
• As a Retailer, I should be able to track product sales and returns.

User Personas

• Retailer: The primary user of the system, responsible for managing inventory, updating product information, and ensuring stock levels meet demand.

Core User Flows

• Retailer adds a new product -> Inputs product details -> Saves product to inventory.
• Retailer updates product information -> Modifies details such as price or stock -> Updates inventory.
• Retailer checks stock levels -> Receives low-stock alert -> Reorders stock from suppliers.
• Retailer generates sales report -> Selects report parameters -> Views or exports report.

Signature Design Concept

The "terra-stock" homepage will feature an interactive 3D warehouse environment using @react-three/fiber. Users can navigate through a virtual warehouse where each section represents different product categories. Hovering over a section will display product details, and clicking will zoom into a detailed view of the inventory for that category. This immersive experience will make inventory management engaging and intuitive.

Interaction Model & Motion Direction

The landing page will utilize a "parallax" interaction model, creating a layered depth effect as users scroll through the page. This will be complemented by animated transitions and hover effects to enhance user engagement. Internal pages will adopt a "static" model to prioritize clarity and ease of use for data-heavy tasks.

Non-Functional Requirements

• The system should support concurrent users without performance degradation.
• The application must be accessible on both desktop and mobile devices.
• Data integrity and security must be maintained at all times.

Tech Stack

• Frontend: React for Web
• Backend: Python with FastAPI
• Database: MySQL or MariaDB, using Alembic for migrations
• Local Orchestration: Docker, docker-compose
• Server-side Orchestration: Kubernetes

Assumptions and Constraints

• The application will primarily serve small retailers in India, considering local currency and timezone settings.
• Internet connectivity is assumed to be stable for optimal application performance.
