# Day 42: Building and Managing NoSQL Databases with AWS DynamoDB

Weclome to Day 42. Today we will learn how to build and manage NoSQL Databases with AWS DynamoDB.

### What is DynamoDB?

**Amazon DynamoDB** is a **fully managed NoSQL database service** provided by **AWS (Amazon Web Services)**. It is designed to store and retrieve large amounts of data **very fast**, with **high availability** and **automatic scaling**, without you needing to manage servers.

## 🔹 Key Characteristics of DynamoDB

### 1️⃣ NoSQL Database

* Stores data as **items** (similar to rows)
    
* Items are grouped into **tables**
    
* Uses **key–value** and **document** data models
    
* Schema is flexible (attributes can vary per item)
    

---

### 2️⃣ Fully Managed by AWS

You **don’t manage**:

* Servers
    
* Operating systems
    
* Patching
    
* Backups
    
* Scaling
    

AWS handles all of this automatically.

### 3️⃣ Extremely Fast Performance

* Single-digit **millisecond latency**
    
* Designed for **high-traffic applications**
    
* Handles millions of requests per second
    

---

### 4️⃣ Highly Scalable

* Automatically scales **read and write capacity**
    
* Supports **on-demand** and **provisioned** capacity modes
    

---

### 5️⃣ High Availability & Durability

* Data is **replicated across multiple Availability Zones**
    
* Built-in fault tolerance
    
* Designed for **99.999% availability**
