    • Volume of data in the billions

The last chapter of the book ‘Your Career in Data Science’ is pure gold for anyone aspiring to be a Data Scientist.

This book is a must for a SQL Server DBA looking at other career paths and opportunities. The book is an easy yet fascinating read. One of the few technical books that I could not put down. It’s packed with great information and the book can be found at a reasonable price.

On a personal note, I started as a math major and took alot of classes on statistics. I eventually switched to Computer Science as the job prospects in mathematics were limited back in the 1970’s. Data Science is a new frontier that needs to be considered for your SQL Server DBA career path. I’m not sure I would jump into Data Science, even back then, but it might be just what your career needs.
