The book also covers how to design your IOT solution around your data. Not only will you learn more about MySQL, but you will also see how best to deploy MySQL in your IOT solution using low-cost computer boards such as the Raspberry Pi, Beaglebone Black, Intel Galileo, and more.
Finally, the book will give you a thorough overview of how data can be augmented and annotated to make it easier to glean the golden nuggets of knowledge you seek while wading through your sensor data.
