Fair trade for the winners!
The Fair Trade Company buys products from local producers (e.g. coffee, rice) and resells them throughout a single e-commerce platform.
Strategical DDD
There are many bounded contexts, but we're going to focus on 3 of them:
- Sales
- Stock Management
- Purchasing
Events
| Sales | Stock Management | Purchasing | |
|---|---|---|---|
| ProductSold | emits | consumes | |
| ProductStockUpdated | consumes | emits | consumes |
| ProductPurchased | consumes | emits | |
| … |

Architectural hint
- Modular monolith is your friend!
- In memory databases will work fine.
- Also, a very basic (no topic) synchronous
