Sign in to **AWS Management Console** as an **IAM User**

**Pre-requisite** - Ensure you have selected the AWS region closest to your location\
For this guide, we will be using us-east-2 (Ohio) as a preferred choice

Type **DynamoDB** in the search bar and click on **DynamoDB** to view the **DynamoDB** Dashboard

**What is DynamoDB in AWS?**

Amazon DynamoDB is a fully managed NoSQL database service provided by Amazon Web Services (AWS). It is designed to provide high performance, scalability, and availability for applications that require low-latency access to large datasets. DynamoDB is a key component of AWS's database offerings and is widely used for a variety of use cases, ranging from mobile and web applications to gaming, IoT (Internet of Things), and more.

On the **DynamoDB** dashboard click on **Tables** from the left bar to view the Tables

Tables wizard will open, On the top right corner click on the **Create table** button  

**Create table** wizard will open, scroll to the **Partition key** section and type "**name**" in the text input field with **String** Data type

**What is the Partition key in Amazon DynamoDB?**

A partition key is a primary attribute that is used to distribute data across multiple partitions in the underlying storage infrastructure of DynamoDB. Every item in a DynamoDB table must have a unique partition key value, and DynamoDB uses this partition key to determine the partition in which the item will be stored.

On the **Sort key** section type "**city**" in the text input field with **String** Data type

**What is the Sort key in Amazon DynamoDB?**

A sort key is an optional attribute that is part of the primary key for a table. While the partition key is required, the sort key is not, but it becomes relevant when you need to specify a sort order for items within a partition.

Scroll to the **Table settings** section, select the option **Customize settings** 

Scroll to the **Secondary indexes** section and click on the **Create local index** button

**What is Secondary indexes in Amazon DynamoDB?**

In Amazon DynamoDB, secondary indexes are additional data structures that allow you to query and retrieve items from a table using attributes other than the primary key. While DynamoDB tables are initially indexed on the primary key (either the partition key or a composite of partition key and sort key), secondary indexes provide flexibility by enabling queries based on different attributes, thus supporting various access patterns.

**New local secondary index** wizard will open, give "**country**" in the text input field for the Sort key with **String** Data type

Give "**country-index**" as the Index name in the text input field and click on the **Create index** button to create Local secondary index
