Joe Celko's Analytics and OLAP in SQL (The Morgan Kaufmann Series in Data Management Systems)

There's very little useful information in here beyond what you'll find in Celko's SQL for Smarties book, which is a good reference, albeit full of errors. What's especially disappointing to me is that several sections from that book were moved into this new volume, but only lightly edited, if at all, thereby perpetuating many typos and technical errors from several editions ago. Technical books really need better editing if they're going to be good teaching tools, otherwise they just wind up misleading and frustrating the reader. In this case, I feel like I bought a bunch of outtakes and remixes from an artist whose recording contract demanded additional albums when only the first was truly inspired.

As he always does, Joe Celko gets right to the point in this amazing review of all one needs to know about OLAP databases and SQL development. I'm already passing this copy to my entire development team. Great work and no BS.Thanks to Joe Celko

I found this gem in the usual aisles at my favorite bookstore among other technical books. Yet, this is a book on SQL, OLAP, Warehouse and metrics that is great because "he cuts to the chase". So many technical books have way too much information and boring paragraphs with little real world examples or insights or lessons learned.If you enjoy databases and data analysis, this book is great. I'm going to check out other books by this author because I think he is on to something in providing information and insights to technical domains.Great job!

Ideal para las personas que tienen experiencia en base de datos y desean introducirse en el mundo de los sistemas de análisis de datos. No es un libro para todo tipo de público ya que requiere ciertas habilidades en SQL, específicamente sobre vistas y agrupaciones. Ampliamente recomendado.
