Tables, Items, and attributes are its core concepts. A table is a collection of items, and each item is a collection of attributes.
Tables are similar to SQL databases but don’t have a fixed schema.
Each row in a DynamoDB table is called an Item - fundamentally JSON documents with key-value pairs.
These key-value pairs are also referred to as Attributes.
Every Item must have a primary key, uniquely identifying that item in the table.
DynamoDB supports two kinds of primary keys.
A simple primary key composed of one attribute known as the partition key
A composite primary key, composed of two attributes referred to as partition key and sort key
Try DynamoDB for fast, flexible NoSQL data storage!
