Using Open Source Platforms for Business Intelligence: Avoid Pitfalls and Maximize ROI (The Morgan Kaufmann Series on Business Intelligence)
"Finally, a book focused entirely on Open Source BI (OSBI).  Lyndsay has done a great job tackling this complex subject and making it digestible by both business and IT.  She discusses the benefits and challenges to choosing OSBI compared to traditional enterprise BI software, in a fair and unbiased approach.   It's worth reading for all those considering OSBI for all, or part of their BI architecture."-Steve Dine,Datasource Consulting, LLC
