Fundamentals #2: Introduction to Domain Modeling

In this video, Gareth walks you through the process of modeling your domain with a focus on data and relationships, specifically for your eShop system. We create entities for Orders, Order Lines, and Products, establishing important one-to-many and many-to-one relationships that reflect ownership and cascading deletes. Gareth also discusses the implications of these relationships on our architecture, particularly in a relational database context. Additionally, we touch on the need for customer associations, addresses, and order statuses. Please ensure you follow along and apply these concepts as we prepare for the next workshop on setting up services to act on this domain. 00:00 | Introduction to Domain Modeling 01:57 | One-to-Many Relationship Explained 06:30 | Customer-Order Relationship Dynamics 08:39 | Adding Address Entity 10:30 | Delivery and Billing Addresses 13:16 | Product Category Relationship
