CompTIA DataSys+ Study Guide: Exam DS0-001 (Sybex Study Guide)

I got the book to establish foundational knowledge and thought it was well written. I won't bother taking the exam because 369 USD (at the time of this review) is not worth it for what is basically a vocab test.

Lets me start by saying I have a degree in data analytics so I do have a strong background for the CompTia exam from the start. That being said this was a great resource to learn what areas you might need to improve in for the test. Definitely would recommend. With the practice test online being probably the best part.
