Raj's introduction !!
I will provide you an outline of the course and make suggestions on how to get the most out of this course
Setup local development environment
You will learn about NoSQL Workbench capabilities
You will get hands on experience with using CLI and Workbench against the local DynamoDB
Setup VSC and clone the course repository
In this lesson I will provide you a logical view of the DynamoDB service and introduce you to basic terminology.
Learn how DynamoDB pricing works. You learn the terms WCU/RCU/WRU/RRU
Learn about the two capacity modes supported by DynamoDB.
In this exercise you will experiment with capacity modes
DynamoDB is NOT type-less, it supports multiple types of data
In this exercise you will create a simple model
Learn about the control & data plane operations
Learn the DynamoDB Control Plane API
Learn how Item Writes work under the covers
Learn about the data plane API
Set BatchWriteItem API in action
Learn how Reads work under the covers
Checkout the GetItem, Scan and BatchGetItem in action
Learn how queries are processed and how to use the query operation
Learn how Update and Deletes work under the covers
Try out the UpdateItem and DeleteItem API
Try the DeleteItem and BatchWriteItem API
Learn how to use PartiQL queries with DynamoDB
Learn the differences between Relational database indexes and DynamoDB indexes. Learn about the types of indexes and which one to use when.
Deep dive into LSI
Try out an LSI
Deep dive into GSI
Try out a GSI
Learn the ideas behind Single Table Design and why it is important to use it for DynamoDB
Learn the process of Single Table Design/modeling process
ACME Bank is a fictitious company that has decided to use DynamoDB for their retail banking systems. You are the lead architect who is given the responsibility to design the DynamoDB data model.
In this lesson we will go deeper into ERD and Access patterns that need to be addressed with DynamoDB model
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
