Amazon DynamoDB Data Modeling for Architects & Developers

Note:

This course does NOT use AWS console for showing you basic DynamoDB operations
This course does NOT focus on just coding

This course primarily focusses on Data Modeling practices and patterns for Amazon DynamoDB. You will learn DynamoDB best practices, tips and techniques for building modern and cost effective applications/microservices. At a high level, course is divided into 2 parts:

Part-1 Objective: Build a solid understanding of DynamoDB

How DynamoDB works under the covers?
Hands-on exercises to try out the DynamoDB API(s) using CLI and Python code
Feature/capability comparison with relational database

Part-2 Objective: Learn to apply DynamoDB design patterns

Learn DynamoDB data modeling process
How to apply patterns to address business requirements
Analyze the access patterns and identify the right pattern to use
Hands-on exercises to build a data model for a banking use case (refer: ACME case study)

Tools in use

NoSQL workbench
Local DynamoDB for model development & testing
AWS cloud account for testing (minimal use)
An integrated development environment (like Visual Studio Code)
Python – if you would like to run the code samples on your machine
Git client

Is this course for me?

Yes – if you are an Architect responsible for designing apps on DynamoDB

Yes – if you are a Developer and aspiring to become an architect

Yes – if you are a DBA and looking to expand your skills to NoSQL databases

Yes – if you are a Technologist who is curious on how DynamoDB works under the covers

No – if you are just looking for basic “How-to” tutorial on DynamoDB

No – if you are looking for coding guidance DynamoDB apps

Course approach

Course does not assume that you already know DynamoDB. For that reasons, I am first covering the basics of DynamoDB. But unlike other courses, I will not just show you how-to use DynamoDB rather I will show you how DynamoDB works under the covers !! I strongly believe that to effectively use a database, an architect MUST understand how database technology works under the covers.

Data modeling is an iterative process. I am sharing a prescriptive guidance on the process and then showing step-by-step how to apply the process. As a case study I am using an example of ACME bank (a fictitious retail bank). Throughout the course we will be applying the process to ACME bank use cases to evolve a full blown DynamoDB data model.

Case study : ACME Bank

A fictitious bank that has embarked on a journey to modernize its retail banking systems. You are the Lead Architect for the retail banking modernization initiative. It is your responsibility:

To work with business owners to understand the requirements
To model the data for DynamoDB
Prove/Disprove that DynamoDB will meet the application needs
Educate stakeholders on DynamoDB capabilities
Help ACME Bank CTO to make a decision on whether to use DynamoDB or not

How long do I have access to the course materials?

You can view and review the lecture materials indefinitely, like an on-demand channel.

Can I take my courses with me wherever I go?

Definitely! If you have an internet connection, courses on Udemy are available on any device at any time. If you don't have an internet connection, some instructors also let their students download course lectures. That's up to the instructor though, so make sure you get on their good side!
