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.

Ubiquitous Language

It isn't a coincidence that the website of Eric Evans, the author of the original DDD book, is located at http://domainlanguage.com. Fundamental concepts of DDD, such as Ubiquitous Language and Bounded Context, are both based on the idea of language. It might sound strange to those who haven't spent many years developing software because, for less experienced developers, the only language that's important is a programming language. We learn to program usually by studying some concepts and applying them to practice using one of the programming languages. We think that we can translate a human language into a programming language, and this is the essence of our work. There's some degree of truth there indeed. However, this is by far not the essential part of the developer's daily routine.
