MongoDB Use Cases in E-commerce

Introduction

MongoDB is widely used in e-commerce applications due to its flexible schema design, scalability, and high performance. This tutorial covers various use cases of MongoDB in e-commerce, demonstrating how it can be utilized to build robust and scalable e-commerce platforms.

Product Catalog

MongoDB's flexible schema makes it ideal for storing product catalog data, which can vary greatly between different products.

Example: Product Document

{
    "_id": ObjectId("507f1f77bcf86cd799439011"),
    "name": "Smartphone",
    "brand": "BrandName",
    "price": 299.99,
    "description": "A high-quality smartphone",
    "category": "Electronics",
    "specifications": {
        "screenSize": "6.1 inch",
        "battery": "3000mAh",
        "camera": "12MP"
    },
    "stock": 50
}

Customer Data

Store and manage customer data, including personal details, order history, and preferences, in MongoDB.

Example: Customer Document

{
    "_id": ObjectId("507f1f77bcf86cd799439012"),
    "name": "John Doe",
    "email": "john.doe@example.com",
    "password": "hashed_password",
    "address": {
        "street": "123 Main St",
        "city": "Anytown",
        "state": "CA",
        "zip": "12345"
    },
    "orderHistory": [
        { "orderId": "1001", "date": "2023-01-15", "total": 59.99 },
        { "orderId": "1002", "date": "2023-02-20", "total": 120.00 }
    ],
    "preferences": {
        "newsletter": true,
        "smsNotifications": false
    }
}

Order Management

Manage orders and transactions efficiently with MongoDB's support for ACID transactions.

Example: Order Document

{
    "_id": ObjectId("507f1f77bcf86cd799439013"),
    "customerId": ObjectId("507f1f77bcf86cd799439012"),
    "items": [
        { "productId": ObjectId("507f1f77bcf86cd799439011"), "quantity": 2, "price": 299.99 }
    ],
    "total": 599.98,
    "status": "Shipped",
    "shippingAddress": {
        "street": "123 Main St",
        "city": "Anytown",
        "state": "CA",
        "zip": "12345"
    },
    "orderDate": "2023-03-10",
    "deliveryDate": "2023-03-15"
}

Inventory Management

Track inventory levels and manage stock with MongoDB's flexible data model.

Example: Inventory Document

{
    "_id": ObjectId("507f1f77bcf86cd799439014"),
    "productId": ObjectId("507f1f77bcf86cd799439011"),
    "warehouseLocation": "Warehouse A",
    "stock": 50,
    "reorderLevel": 10,
    "supplier": "SupplierName"
}

Personalization and Recommendations

Use MongoDB to store and analyze customer behavior data for personalized recommendations.

Example: Recommendation Document

{
    "_id": ObjectId("507f1f77bcf86cd799439015"),
    "customerId": ObjectId("507f1f77bcf86cd799439012"),
    "recommendedProducts": [
        { "productId": ObjectId("507f1f77bcf86cd799439011"), "score": 0.95 },
        { "productId": ObjectId("507f1f77bcf86cd799439016"), "score": 0.85 }
    ]
}
