A CRUD (Create, Read, Update, Delete) operations project using API Gateway, AWS Lambda, and DynamoDB involves several steps. In this project we build a RESTful API that interacts with a DynamoDB table to perform CRUD operations on items in the table. Below is the high level design: The POST method on the DynamoDBManager resource supports the following DynamoDB operations:

• Create, update, and delete an item.
• Read an item.
• Scan an item.
