Hands-On Domain-Driven Design with .NET Core

By: Alexey Zimarev

Overview of this book

Developers across the world are rapidly adopting DDD principles to deliver powerful results when writing software that deals with complex business requirements. This book will guide you in involving business stakeholders when choosing the software you are planning to build for them. By figuring out the temporal nature of behavior-driven domain models, you will be able to build leaner, more agile, and modular systems. You’ll begin by uncovering domain complexity and learn how to capture the behavioral aspects of the domain language. You will then learn about EventStorming and advance to creating a new project in .NET Core 2.1; you’ll also and write some code to transfer your events from sticky notes to C#. The book will show you how to use aggregates to handle commands and produce events. As you progress, you’ll get to grips with Bounded Contexts, Context Map, Event Sourcing, and CQRS. After translating domain models into executable C# code, you will create a frontend for your application using Vue.js. In addition to this, you’ll learn how to refactor your code and cover event versioning and migration essentials. By the end of this DDD book, you will have gained the confidence to implement the DDD approach in your organization and be able to explore new techniques that complement what you’ve learned from the book.

EventStorming

Discovering domain terminology is essential, and this terminology becomes a part of the Ubiquitous Language. However, the process of discovery can be rather lengthy and not always successful. When we discuss how the business works and what problems we are going to solve by writing software, too often the conversation comes down to discussing the features that the business is keen to implement. A set of features, of course, can be called software, but it does not necessarily form a system. Furthermore, to build a comprehensive solution for a particular problem, more system-level thinking is required.

Thinking in systems is only briefly covered in this book. To know the subject better, please refer to great books on this topic like the classic An Introduction to General System Thinking by Gerald Weinberg and Thinking in Systems by Donella H. Meadows, et al.
