Data is an area of technology I really didn't get much into. Interestingly enough, the first consulting methodology I learned was called ISP (Information Strategy Planning) way back when. At the time, DW has come on the scene and (at least in Korea), our practice worked on enterprise data modeling quite a bit. Since then, there were many change to work on the application side, but not data so much. Anyway, I am heading into a new engagement and I aim to focus on data.
So starting with a primer. This book does a good job of providing an overview and explains the major concepts well. The pictures are pretty cheesy in most part and downright stupid for few (e.g., picture of children's sandbox to depict concept of development sandbox), but all well intentioned. All in all, I liked the book and picked up many key concepts.
