Pentaho Solutions: Business Intelligence and Data Warehousing with Pentaho and MySQL ReviewJos and Roland have done a great job explaining the tools and technology of the Pentaho BI Platform in the context of building real world Business Intelligence applications. They have taken some very complicated and technical concepts and presented them in an easy to follow case study. The case study they chose is simple to understand yet filled with the same kinds of real world complexities that make BI applications difficult to deliver.
The "Getting Started with Pentaho" section has all the information and documentation you wish you could find neatly arranged on the Pentaho community site. They do an excellent job explaining the entire Pentaho application stack from collecting data to presenting information. The book could have stopped here, being the Pentaho missing manual, and still have been worth buying.
The next section, "Dimensional Modeling and Data Warehouse Design" is an very good introduction/refresher on hows and whys of building data warehouses, data marts and OLAP cubes. Again they have taken a subject that is broad and complex and presented it in a way that is easy to understand and apply. Where appropriate, they refer the reader to other resources available for more in-depth coverage of specific topics.
A data warehouse is useless until you can reliably get good, complete and accurate data into it. The section on "ETL and Data Integration" is another section that could easily stand on it's own. After an introduction to ETL and Pentaho Data Integration, they show how to populate the database used for the case study including populating time dimensions. Other real world topics touched upon include; change data capture, data validation, data cleansing and issues with generating dimension tables.
The last section covers transforming data into information via metadata, reporting, analysis services, data mining and dashboards. Each topic is covered by an introduction, explanation of the tools available and examples using data from the case study.
I like the way Roland and Jos combine general BI knowledge with tutorials on the Pentaho applications and tie it all together with an interesting case study giving you a chance to stop and play as you follow along. I also enjoyed the many side notes with tidbits of history and pointers to other resources. Overall I found this book both informative and enjoyable.
I'm a fifteen year veteran of building BI software, one of the original Pentaho developers and am currently the Pentaho community guy. I'm not affiliated with Jos, Roland or Wiley and receive no benefit from this book beyond the satisfaction of having Pentaho software be so well represented.

Beautiful Visualization: Looking at Data through the Eyes of Experts (Theory in Practice) ReviewI am relatively new to creating data visualizations, so I was very curious to see what kinds of ways I could express data by reading about what experts do. Beautiful Visualization is an excellent resource, mostly for those who are not novices like myself, but regardless, is a wonderful learning tool.
The chapters are written by different people, each with different methodologies and tools that they use to visualize data. Several chapters include sample code or suggested applications you can use to create visualizations, most of them open source. A key thread throughout the course of this book is using visualization to tell stories that may not otherwise be told or realized by simple data evaluation.Beautiful Visualization: Looking at Data through the Eyes of Experts (Theory in Practice) Overview
Visualization is the graphic presentation of data -- portrayals meant to reveal complex information at a glance. Think of the familiar map of the New York City subway system, or a diagram of the human brain. Successful visualizations are beautiful not only for their aesthetic design, but also for elegant layers of detail that efficiently generate insight and new understanding.

This book examines the methods of two dozen visualization experts who approach their projects from a variety of perspectives -- as artists, designers, commentators, scientists, analysts, statisticians, and more. Together they demonstrate how visualization can help us make sense of the world.
