This book is remarkable in that it describes a complete process of analysis activities and describes how to solve a particular problem. Along with descriptions how to build charts and visual elements Karl described the question about what type of chart is best to use in each case, what conclusions can be drawn, and how to do it effectively.
In fact author offered six rules for building any application:
1. use adequate labeling
2. convert color into data
3. add more detail
4. throw away chartjunk
5. respect usability
6. be honest
As a result, you will get a fairly complete picture of what and how you can build in QlikView, but the most important – what the business gets from its use.
In general, the book is excellent. I recommend it everyone to read. I think that novice developers will be able to understand exactly what the business needs. Professionals will be able to see other possible approaches as to how to make better do certain things, or even find something new.
