You cannot explain enterprise development by walking us through one application! They needed to explain why they have designed a component in a particular way, and possible alternatives for different scenarios.

The books is basically a walkthrough of an application written by the authors. I was hoping for something along the lines of a discussion of designing an implementing enterprise applications.

I think their data access mechanism is better than hard coding sql but I wouldn't use it in production. It is not a true object orientated persistence layer.

However I rate this book 2 stars because their are some things that I gained from their example app. There are always things to learn from analyzing an application.
