Introduction

The Database Schema Overview provides a comprehensive structural analysis of the TAMV Online project's data persistence layer. This system is designed to handle complex relationships between users, products, and system configurations, serving as the foundational backbone for what is described as a highly ambitious integrated system.

The database architecture ensures data integrity and supports the core functionalities of the application, including user management and product cataloging. It utilizes a relational model to maintain consistency across the platform's various modules.

Core Entities and Relationships

The system is built around several key entities that define the operational scope of the TAMV Online platform. The primary relationships involve users who interact with the system and the products managed within it.

Entity Relationship Diagram

The following diagram illustrates the primary entities and their cardinality within the system.

Data Models

User Management

The User model defines the structure for identity and access management. It includes fields for authentication and profile metadata.

Field	Type	Constraints	Description
id	Integer	Primary Key, Auto-increment	Unique identifier for each user
username	String	Unique, Not Null	Unique handle for login
email	String	Unique, Not Null	Verified contact and login email
password_hash	String	Not Null	Securely hashed user password

Sources: src/models/User.js:5-25, database/schema.sql:10-20

Product Inventory

The Product model facilitates inventory management and catalog display.

Field	Type	Constraints	Description
id	Integer	Primary Key	Unique product identifier
name	String	Not Null	Display name of the item
price	Decimal	Not Null, > 0	Unit price of the product
stock_quantity	Integer	Default 0	Current available items in stock

Configuration and Connectivity

The database connection is managed through a centralized configuration file that handles environment-specific parameters.

// Example configuration structure derived from src/config/db.config.js
module.exports = {
  HOST: process.env.DB_HOST || "localhost",
  USER: process.env.DB_USER,
  PASSWORD: process.env.DB_PASSWORD,
  DB: process.env.DB_NAME,
  dialect: "postgres",
  pool: {
    max: 5,
    min: 0,
    acquire: 30000,
    idle: 10000
  }
};

Sources: src/config/db.config.js:1-15

System Data Flow

The data flow within the database layer follows a standard request-response pattern where the application models interact with the persistent storage via an ORM or direct drivers.

Conclusion

The Database Schema for TAMV Online is structured to support a robust and scalable environment. By defining clear boundaries between user identity and product inventory, the system ensures that data remains consistent and accessible for the ambitious goals of the project.
