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.

Language and context

In the introduction of this chapter, we already touched on the topic of linguistic differences in the same language. If one language is divided by some boundary, be it a geographical, national, or professional area, it starts to split. We used British and American English as an example before, but of course, there are more examples like this. Dutch language spoken in Belgium is often even referred to as a separate language, Flemish because it sounds different, but mainly because, for everyday objects and actions, different words are being used. The same can be observed for languages that evolve within professional groups where people develop jargon, and we've looked at some examples of this too.

These examples were presented here to demonstrate how important it is to define the precise meaning of words. Avoiding confusion is indeed one of the goals in...
