Sample eCommerce application using Domain Driven Design

DDDMart

This is a small sample application for a fake eCommerce company (DDDMart) which uses Domain Driven Design techniques for modelling the domain.

The application focuses on the core Domain layer so does not have any APIs. There are a lot of different opinionated ways to host domain models through an API and I specifically wanted to focus on modelling the domain and how Domain and Integration events are handled.

The DDDMart console application hosts a number of background services which are used to simulate how an Order is generated and paid using the different bounded contexts.

Sub-Domains

The domain is made up of 3 sub-domains:

• Catalogue (Core) - Product catalogue
• Ordering (Core) - Used for creating a Basket and creating an Order of different Products
• Payments (Supporting) - Used for generating and tracking Invoices and storing customer Payment Methods

Each sub-domain is made up for 1 or more bounded-contexts. The application has been layer to allow each sub-domain to be hosted as a separate microservice.
