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.

The single model trap

Let's take a look at how software usually starts its life, when developers first get their hands on keyboards and start writing code, hoping to build something useful. We will follow the usual progress that software companies (or IT departments) make while addressing the needs of their users, over the years they spent, working to make the software more useful, adding features and fixing issues. What I describe next is the usual evolutionary growth of software solutions that can be found everywhere. It is possible that some parts of the picture that I am going to paint will be recognizable to you and will resonate with your experience.

Starting small

We rarely find ourselves working for a company...
