Bought this book while I was preparing for my "70-463 Implementing a Data Warehouse with Microsoft SQL Server 2012" certification. It does not cover all the topics(such as DQS, MDS) required for the exam, but all the SSIS 2012 features are explained clearly with Step by step examples. Enjoyed reading through and practicing.
E-book was given free when hard copy was bought from "PACKT publishing" website. Hard copy arrived after I finished my exam(3 weeks after ordering). It was the e-book that I had read through.
