Book Club: Implementing Domain-Driven Design Ch 12 part 2

This is the seventh session of our Implementing DDD book study.

We'll discuss part 2 of Chapter 12, Repositories.

Coding Collaboration:

We've also decided to collaborate on writing some code for the .NET version of Vaughn Vernon's book samples at its GitHub repo. If interested to participate on this aspect, please comment in this page and we'll figure out the best way to go about it. (In person, Google Hangouts, whatever, etc)


Session 7:


12: Repositories


GoToMeeting Info:

Will be posted here shortly before start time.


Full Details:

Domain-Driven Design community leader Vaughn Vernon recently published Implementing Domain-Driven Design! Book summary:

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 examples–all applicable to C# developers–and 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 Entities–and learning when to use Value Objects instead

> Mastering DDD’s powerful new Domain Events technique

> Designing Repositories for ORM, NoSQL, and other databases
