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 previous chapter, we discussed the importance of language briefly. In the software industry, we developed this naïve perception that the only languages that matter are programming languages. That's why we often speak complete gibberish and our colleagues from other departments, or our customers, have a hard time understanding what we're trying to say. This issue is mutual because many lines of business have developed their jargon, which other people might not completely understand.

In this chapter, we're going to go deeper into the importance of language and go through several examples of mockups and code. We'll also get into the concept of language in a context and introduce the Ubiquitous Language, one of the most critical aspects of Domain-Driven Design (DDD).

In this chapter, we'll go deeper into the following topics...
