# Amazon DynamoDB Deep Dive Course

## Pinehead Records Sample Web App Evolution

### [webapp-v0](./webapp-v0) - Relational/Legacy

- Relational model in MySQL

- limited optimizations

- limited caching

- no indexes

- inefficient queries

- images stored on local filesystem

- accounts in DB

### [webapp-v1](./webapp-v1) - Fundamental DynamoDB

- Naïve migration from CSV to DynamoDB

- 3 DDB tables mimicking the relational structure

- images are moved to S3 with URI in DDB attribute

- no indexes

- accounts in DB

### [webapp-v2](./webapp-v2) - Intermediate DynamoDB

- some optimizations

- better table structure (single hierarchical table)

- indexes

- transactions

- accounts in DB

### [webapp-v3](./webapp-v3) - Advanced DynamoDB

- federated web identity (Cognito)

- fine-grained policies

- triggers

- improved security

- DAX
