PRICE INTEL System Requirements Document

1. Introduction

This document outlines the system requirements for the PRICE INTEL project, which aims to build a production-grade backend for a competitor price monitoring platform called "PriceIntel". The initial deployment will target Furniture Village UK, focusing on real persistent data and scalability.

2. System Overview

2a. Product Interpretation and Delivery Boundary

• Domain Descriptors:

  • Backend Development: Focus on building a robust backend system for PriceIntel with a confidence level of 0.9.
  • Database Architecture: Design and implement a scalable database schema with a confidence level of 0.9.

• Project Scope:

  • The PRICE INTEL project focuses on delivering a backend foundation for a production-grade competitor price monitoring platform.
  • Excluded Assumptions: Frontend development and mock/demo data usage are not part of the current scope.

• Custom Pages:

  • No custom UI pages are included as the focus is solely on backend processes.

• Access:

  • The access is application-owned, with no persistent identity or authentication required.

• Behavior Contracts:

  • Module Development:

    • Actor: Developer
    • Trigger: Start module coding
    • Inputs: Module specifications
    • Outcomes: Modules for database, product model, competitor model, price history, scan jobs, configuration, logging, error handling created
    • State Changes: None
    • State Lifetime: None
    • Identity Continuity: None
    • Audience Entry: Internal
    • Failure Outcome: Module development errors

  • Build and Test Execution:

    • Actor: Developer
    • Trigger: Run build and tests
    • Inputs: Codebase
    • Outcomes: Build successful, Tests passed
    • State Changes: None
    • State Lifetime: None
    • Identity Continuity: None
    • Audience Entry: Internal
    • Failure Outcome: Build or test errors

3. Functional Requirements as Story Points

• As a Developer, I should be able to build the backend foundation for PriceIntel using TypeScript/Node.js and PostgreSQL. explicit
• As a Developer, I should be able to create the necessary database tables: products, competitors, competitor_products, price_history, scan_jobs, scan_results, alerts, and system_settings. explicit
• As a Developer, I should be able to create clean modules for database, product model, competitor model, price history, scan jobs, configuration, logging, and error handling. explicit
• As a Developer, I should be able to add migrations and seed only the competitor configuration. explicit
• As a Developer, I should ensure the system supports scalability for thousands of products and multiple competitors. explicit
• As a Developer, I should be able to run the build and tests and fix any errors. explicit

4. User Personas

• Developer: Responsible for building and maintaining the backend system for PriceIntel. This persona handles module development, database management, and system testing.

5. Core User Flows

1. Developer Builds the Backend System:
   • The developer starts coding the modules based on specifications.
   • The developer creates the necessary database tables.
   • The developer implements clean modules for various backend functionalities.
   • The developer adds migrations and seeds the competitor configuration.
   • The developer runs the build and tests to ensure the system functions correctly.

6. Visuals Colors and Theme

A first-party web theme is not applicable as the project focuses solely on backend development without a custom UI.

7. Signature Design Concept

The design concept is not applicable as the project focuses on backend processes without a user interface.

8. Interaction Model & Motion Direction

The interaction model is operational, focusing on backend processes such as module development, database management, and system testing. There is no decorative motion or frontend interaction.

9. Non-Functional Requirements

• The system must support scalability for thousands of products and multiple competitors. explicit
• The system must use real persistent data, not mock/demo data. explicit

10. Tech Stack

• Backend: TypeScript/Node.js
• Database: PostgreSQL

11. Assumptions and Constraints

• The project will not include frontend development.
• The focus is on delivering a production-grade backend system with real persistent data.

12. Glossary

• Developer: The individual responsible for building and maintaining the backend system for PriceIntel.
• Backend Foundation: The core infrastructure and modules required to support the PriceIntel platform.
• Scalability: The ability of the system to handle an increasing number of products and competitors efficiently.
