# ES/CQRS Workshop
## Intro
Hello, my name is [Ronaldo](http://github.com/ronaldofs) and I'm a software designer and developer, proud dad and guitarist wannabe.
I work @ [Subvisual](https://subvisual.com) where we focus on helping ventures jumpstart or scale their business, be it strategy or hands-on, currently collaborating on several projects in web3/blockchain space.
## Overview
In this workshop, we'll build a backend application in Elixir where the main goal is to showcase and discuss Event Sourcing and CQRS in the context of "real-world" business problems.
We'll cover strategy, planning and specification for a selected and scoped business domain and analyse implementation patterns and trade-offs for each component of the final solution.
**Topics covered:**
- Domain-driven Design
- Domain/subdomain
- Ubiquitous language
- Bounded context
- Continuous collaboration
- Tactical patterns
- Event Sourcing and CQRS
- CRUD
- Events and Streams
- Event Store
- Projection
- Process manager / Saga
- Collaborative modeling
- Event Storming
- Event Modeling
- Context Mapping
- User Story Mapping
- Value Stream Mapping
- Process
- Delivery vs Discovery
