Overview
Amazon DynamoDB is a managed NoSQL database service.
Table
A table is a collection of items. A table contains zero or more items. An item is a group of attributes that is uniquely identifiable among all other items. Items are similar in many ways to rows, records or tuples in other database systems. There is no limit to the number of items that can be stored in a table.
Item
An item is a collection of attributes.
Primary Key
DynamoDB uses primary keys to uniquely identify each item in a table.
Attribute
An attribute is a fundamental data element, something that does not need to be broken down any further.
