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.

International trade products and services

International trade is fraught with risk, which then presents a degree of uncertainty over the timing of payments between the seller (exporter) and the buyer (importer), especially due to a lack of trust between the parties involved. For exporters, until payment is received, all sales are gifts. Consequently, exporters prefer receiving payment as soon as the order is placed or at least before the goods are shipped. For importers, until the goods are received, all payments made toward a purchase are donations. Consequently, importers prefer receiving goods as soon as possible and delaying payment until the goods are resold to generate enough money to pay the seller.

This situation presents an opportunity for trusted intermediaries (such as KP Bank) to play a significant role in brokering international trade transactions in a secure manner. KP bank offers a number of products to facilitate international trade payments, as listed here:
