Create a DynamoDB table and perform various table operations using NoSQL Workbench

Lab Details

  1. This lab walks you through DynamoDB Console and NoSQL Workbench. You will be creating a DynamoDB table and performing CRUD methods using NoSQL Workbench and visualizing the changes in the DynamoDB console. And also, you will be creating a DynamoDB table in the console and insert items and visualize the reflections in the NoSQL Workbench.

  2. Duration: 60 minutes

  3. AWS Region: US East (N. Virginia) us-east-1


What is AWS DynamoDB?


  • DynamoDB is a fast and flexible NoSQL database designed for applications that need consistent, single-digit millisecond latency at any is a fully managed database and it supports both document and key value data models.

  • It has a very flexible data model. This means that you don't need to define your database schema upfront. It also has reliable performance.

  • DynamoDB is a good fit for mobile gaming, ad-tech, IoT and many other applications.

DynamoDB Tables

DynamoDB tables consist of:

  • Items (Think of a row of data in a table).

  • Attributes ((Think of a column of data in a table).

  • Supports key-value and document data structures.

  • Key= the name of the data.  Value= the data itself.

  • Document can be written in JSON, HTML or XML.

DynamoDB - Primary Keys

  • DynamoDB stores and retrieves data based on a Primary key

  • DynamoDB also uses Partition keys to determine the physical location data is stored.

  • If you are using a partition key as your Primary key, then no items will have the same Partition key.

  • Composite Keys (Partition Key + Sort Key) can be used in Combination.

  • Two items may have the same partition key, but must have a different sort key.

  • All items with the same partition key are stored together and then sorted according to the sort key value.

  • DynamoDB allows you to store multiple items with the same partition keys.

NoSQL Workbench

  •  NoSQL is basically a Non-Relational Database, with a lot of other advantages too.

  • NoSQL Workbench is a virtual development as well as a testing environment for developers across the globe.

  • It allows the users to test their data models over a large number of aspects of functionality and also allows them to develop their software, right from the scratch with ease.

  • In simple terms, the NoSQL Workbench is an IDE platform that includes data modeling, data visualization, and operation building.

  • Data Modeling: Workbench enables users with a facility to build new data models right from scratch or by using existing data models.

  • Data Visualization: As the name suggests, it provides the graphical representation of information and data..

  • Operation Building: Workbench is a strong and reliable platform for building applications and also has a great graphical user interface which eventually makes the communication between the database and the user easier.
