Domain Driven Design

Question

User214117797 posted

Hi all,

Of late, I have been seeing a lot of code written that developers created entity classes purely as a data transfer object. The entity class is essentially a dumb class that serves as a data structure. The developer then creates a static class that manages this entity class, so all the logic and CRUD goes into this static class.

Now, I am not a fan of this as you are creating an unnecessary layer on top and it goes against the founding principles of OOP. I believe this is termed the ananemic model and by some is considered an anti pattern. Regardless, I am not here to start a thread to debate on the pros and cons, rather I am looking for recommendations on a good Domain Driven Design book that I can suggest as supplementary reading material for my developers.

Can any one point me to a good book that will on DDD?

Thanks, Jim

Hello,

probably the most referenced book on DDD is Domain-Driven Design: Tackling Complexity in the Heart of Software by Eric Evans.

Another really good one is Applying Domain-Driven Design and Patterns: With Examples in C# and .NET by Jimmy Nilsson.

My suggestion is to read both of them.

Thanks Garbin.

I will buy those books and get my developers to have a read. 

I have tried explaining to them the benefits of a rich domain model but they just cant get their heads around it. Maybe I am just awful at explaining it, so hopefully these books will contrast the stark differences and provide another perspective for them.

Tim McCarthy has written a good book on building an application from start to finish using the ideas of Jimmy and Eric:

NET Domain-Driven Design with C#: Problem, Design, Solution (Programmer to Programmer) by Tim McCarthy

Its a good read and the sample code is a great framework for building applications with a Domain Model. I would read the others first though. Also there is a free book on DDD that summaries Erics book that will get your guys up to speed fast http://www.infoq.com/minibooks/domain-driven-design-quickly.

 You may already know this - by far the best reading is Eric Evans' "Domain-Driven Design - Tackling Complexity in the Heart of Software"

Another very interesting resource is Rob Conery's MVC Storefront - just now being refactored for DDD.
