DDD Value Object: Immutable Value Semantics in the Domain Model
Value objects are a fundamental concept in Domain-Driven Design (DDD), but what exactly are they, and how do you implement them effectively in your applications?
In this video, we take a deep dive into the world of value objects. We explore their characteristics, such as immutability and equality by value, and discuss what makes a well-designed value object.
You'll follow along as I create a reusable base class for value objects in C#, implementing the IEquatable interface to ensure robust equality checks. We'll improve upon the design from Microsoft's microservices architecture guide, refining it for practical use.
As a hands-on example, we implement an Occurrence class, derived from our base class, to demonstrate how value objects can enhance the clarity and integrity of your domain model.
By the end of this video, you'll have a solid understanding of value objects and how to design them effectively using C#. Whether you're new to DDD or looking to refine your approach, this tutorial will provide valuable insights and actionable steps.
