After edition 3 which released July 2017, there have been many contents added. The Power BI from Rookie to Rock Star been such a popular book from the time that it published, and I added content to it every single week. There are some reasons that I thought about writing this book online and writing that for free which I like to mention in this preface. So I thought it would be better to write a book online on this blog rather than spending heaps of time on paper publishing. I’ve been in the publishing process of some books and I am completely aware of that. Publishing a book takes time, writing TOC, then chapters, building demos, peer reviews, proofreading, test, feedback, revise on reviews, and publishing takes a long time. With this fast pace release, any book publishing would be outdated once the book comes out in the market.

However, Power BI is fast-paced technology, Microsoft Product team is doing a great job with monthly, and sometimes even more frequent updates.

The idea of writing a book on Power BI is not new for me, I’ve been thinking about it for a while, even before the first release of Power BI Designer.
