Star Schema The Complete Reference ReviewI always been a great fan of Chris Adamson's writing - and "Star Schema - the Complete Reference" further reinforces this admiration.
The text is a model of clarity, and the book's ideas are organized and presented in a way that rewards the reader with well-chosen examples of escalating dimensional elegance and power as progressively more advance concepts are introduced. Chris deftly and wisely avoids investing too much ink in philosophical discussions of data warehousing architectures, by (correctly) pointing out that dimensional models are universally embraced by all thought-leaders for the "last mile" presentation of information to users. So we best model them correctly - regardless of the upstream plumbing that feeds them.
All of the great dimensional design techniques that we've come to expect from Chris are presented here with added depth and context- including truly great materials on modeling each of the fact table types, and brilliant design approaches for hierarchies and aggregates. But I also appreciate the fact that "Star Schema" bravely addresses really tough dimensional design challenges (multi-valued dimensions, factless facts, derived schemas, and many others) that too often confound and frustrate mere mortal (us) practitioners in the field.
Chris has managed to produce a truly practical dimensional data warehouse design book that is at once irrefutably comprehensive, empowering, and yet eminently readable - a very tough balance to strike. Many thanks and congratulations to him - this is a wonderful and important contribution to the field.

Database Programming With C# ReviewDatabase Programming in .NET is accomplished via ADO.NET which dominates the middle layer of any .NET database application. It can be done via C# or any other .NET language, and there are command line tools as well as Visual Studio.NET to assist the developer. So in a book titled "Database Programming with C#" we expect to find an in depth description of ADO.NET with C# examples demonstrating the use of the classes/methods to accomplish common database tasks.
We can cut this review short by just saying that the author delivers on the expectation with ADO.NET being covered in 2 (out of the 11) chapters. Chapters 3A & 3B describe the connected & disconnected layers and constitute more than a third of the book's size. However, what dominates these chapters and indeed the rest of the book is the many lengthy tables listing methods of the various framework classes. Not only does this get in the way of an enjoyable read but it is just a rehash of the already excellent help system.
Reading this book cover to cover can also become tiresome due to a lot of repetition. The flip-side to this is that the book can be used as a reference text. Claiming the user level to be intermediate-advanced is ambitious although absolute beginners will find an abundance of useful information.
So what do the other chapters cover? The first one claims to be a 'quick intro to C#' but ends up being an overview of .NET in general; The second one introduces databases at the most basic level and really should have been considered prerequisite knowledge (i.e. read Codd, Date or Elmasri etc); the fourth chapter describes VS.NET with its database tools/wizards and the fifth one describes structured exception handling (why?!). There is some good material in chapters 6-8 on stored procedures, views, triggers and message queues. SQLXML is introduced in the appendix but it would have been nice to see more XML coverage throughout the book.
To summarise, if we can leave aside the style and bad organisation of the book, most of the content will more than satisfy beginners.Database Programming With C# Overview
