This is the second and last part of my notes I scribbled down attending the IDDD Tour.

Two weeks ago I got to spend four days attending the IDDD Tour by Vaughn Vernon. Although my book queue has only allowed me to shallowly browse the book, I had high hopes for this course. I anticipated a week of getting lectured on DDD with a few practical exercises, but was blown away by the openne...

decided to provide some integration testing before proceeding as a proof of concept. In integration testing I will connect to the database and perform unit testing while connecting to the database.\ This unit test is almost identical to the one in my previous post. Except here I am testing the r...

Casey Charlton has collected all his article series on DDD in a single downloadable PDF file.

As mention in my previous post that I will be discussing the technical side of **KiGG**. So this is the beginning and it will be a multi-part series. I will try to put as much detail as possible, do let me know if I missed anything. Just for a recap, KiGG is Web 2.0 style social news application ...

In previous post I talked about building domain model for Northwind using Entity Framework. I used the generated ObjectContext class which is NorthwindDataContext as the basic Data Access Layer Helper.
