Domain-Driven Design with Java - A Practitioner’s Guide

By: Premanand Chandrasekaran, Karthik Krishnan

Overview of this book

Domain-Driven Design (DDD) makes available a set of techniques and patterns that enable domain experts, architects, and developers to work together to decompose complex business problems into a set of well-factored, collaborating, and loosely coupled subsystems. This practical guide will help you as a developer and architect to put your knowledge to work in order to create elegant software designs that are enjoyable to work with and easy to reason about. You'll begin with an introduction to the concepts of domain-driven design and discover various ways to apply them in real-world scenarios. You'll also appreciate how DDD is extremely relevant when creating cloud native solutions that employ modern techniques such as event-driven microservices and fine-grained architectures. As you advance through the chapters, you'll get acquainted with core DDD’s strategic design concepts such as the ubiquitous language, context maps, bounded contexts, and tactical design elements like aggregates and domain models and events. You'll understand how to apply modern, lightweight modeling techniques such as business value canvas, Wardley mapping, domain storytelling, and event storming, while also learning how to test-drive the system to create solutions that exhibit high degrees of internal quality. By the end of this software design book, you'll be able to architect, design, and implement robust, resilient, and performant distributed software solutions.

They have been steadily expanding operations to other countries and continents. This has allowed them to expand their international trade business significantly in the last decade. While they have been among the leaders in this space, the recent onset of new digital-native competitors has started to eat into their business and impact their top line adversely. Customers are complaining that the process is too cumbersome, time-consuming, and lately unreliable. In addition, due to a very inefficient manual process that is currently in place, KP Bank has been finding it very hard to keep a check on costs. In just the last 3 years, they have had to increase transaction processing costs by around 50 percent! Not surprisingly, this has coincided with plummeting customer satisfaction, which...
