Material Index Database

🌟 Overview

The Material Index Database is a comprehensive collection of material property data, designed to provide developers and researchers with access to structured material information for engineering, design, and research applications.

This repository contains:

• 📊 Database Schema - Complete database structure and relationships
• 🛠️ SDKs for Multiple Languages - Easy integration with your applications
• 📖 Data Documentation - Comprehensive material data specifications
• 🔧 Database Tools - Utilities for data management and migration

🚀 Quick Start

API Gateway Access

# Material Index API Gateway
https://api.material-index.com/v1

# Database Schema Access
# Access material data through the API gateway
# No direct database access required

SDK Installation

TypeScript/JavaScript

npm install @material-index/database-client

Python

pip install material-index-database

📊 Database Schema

Core Tables

Materials

• Primary Key: id (integer)
• Name: Material name and variations
• Category: Material classification
• Properties: Associated material properties
• Metadata: Creation, updates, and verification status

Categories

• Hierarchical Structure: Parent-child relationships
• Material Classification: Organized material taxonomy
• Slugs: URL-friendly identifiers

Properties

• Property Definitions: Material property specifications
• Units: Measurement units and data types
• Categories: Property classification system
• Searchability: Filterable and searchable properties

Relationships

Materials ←→ Categories (Many-to-One)
Materials ←→ Properties (Many-to-Many)
Properties ←→ Property Categories (Many-to-One)

🛠️ SDKs

TypeScript/JavaScript SDK

import { MaterialIndexAPI } from '@material-index/api-client';

const api = new MaterialIndexAPI({
  baseURL: 'https://api.material-index.com/v1',
  apiKey: 'your-api-key'
});

// Query materials
const materials = await api.materials.list({
  category: 'metals',
  limit: 20
});

// Search properties
const properties = await api.properties.search({
  query: 'density',
  dataType: 'number'
});

Python SDK

from material_index_api import MaterialIndexAPI

api = MaterialIndexAPI(
    base_url='https://api.material-index.com/v1',
    api_key='your-api-key'
)

# Query materials
materials = api.materials.list(
    category='metals',
    limit=20
)

# Search properties
properties = api.properties.search(
    query='density',
    data_type='number'
)
