Implementing Domain-Driven Design

Implementing Domain-Driven Design presents a top-down approach to understanding domain-driven design (DDD) in a way that fluently connects strategic patterns to fundamental tactical programming tools. Vaughn Vernon couples guided approaches to implementation with modern architectures, highlighting the importance and value of focusing on the business domain while balancing technical considerations.

Building on Eric Evans' seminal book, Domain-Driven Design, the author presents practical DDD techniques through examples from familiar domains. Each principle is backed up by realistic Java examplesall applicable to C# developersand all content is tied together by a single case study: the delivery of a large-scale Scrum-based SaaS system for a multitenant environment.

The author takes you far beyond DDD-lite approaches that embrace DDD solely as a technical toolset, and shows you how to fully leverage DDD's strategic design patterns using Bounded Context, Context Maps, and the Ubiquitous Language. Using these techniques and examples, you can reduce time to market and improve quality, as you build software that is more flexible, more scalable, and more tightly aligned to business goals.

Coverage includes

• Getting started the right way with DDD, so you can rapidly gain value from it
• Using DDD within diverse architectures, including Hexagonal, SOA, REST, CQRS, Event-Driven, and Fabric/Grid-Based
• Appropriately designing and applying Entitiesand learning when to use Value Objects instead
• Mastering DDD's powerful new Domain Events technique
• Designing Repositories for ORM, NoSQL, and other databases

For software developers of all experience levels looking to improve their results, and design and implement domain-driven enterprise applications consistently with the best current state of professional practice, Implementing Domain-Driven Design will impart a treasure trove of knowledge hard won within the DDD and enterprise application architecture communities over the last couple decades.

Autorentext

Vaughn Vernon is a champion of simplifying software architecture and development, with an emphasis on reactive methods. He has a unique ability to teach and lead with Domain-Driven Design using lightweight tools to unveil unimagined value. He helps organizations achieve competitive advantages using enduring tools such as architectures, patterns, and approaches, and through partnerships between business stakeholders and software developers.

Klappentext

Succeed with Domain-Driven Design (DDD), today's best-practice framework and common language for making design decisions that accelerate projects, keeping them on track while smoothly incorporating inevitable change. Vaughn Vernon's Implementing Domain-Driven Design builds on Eric Evans' seminal Domain-Driven Design, helping practitioners flatten the DDD learning curve, identify their best opportunities to apply DDD, and overcome common implementation pitfalls. Vernon presents concrete and realistic DDD techniques through examples from familiar domains, such as a Scrum-based project management application that integrates with a collaboration suite and security provider. Each principle is backed up by realistic Java examples, and all content is tied together by a single case study of a company charged with delivering a set of advanced software systems with DDD. Using this book's techniques, organizations can reduce time-to-market and build better software that is more flexible, more scalable, and better aligned to business goals. For software practitioners who are new to DDD, for those who've used DDD but not yet succeeded; and for DDD users who have experienced success and want to become even more effective. Readers will likely include software architects, systems anaysts, application developers, and project managers.
