Chapter 5. Data Analytics Process:
There’s Great Work Behind the Scenes
5.1. Introduction.
5.2. More data,more questions for better answers.
5.2.1. We can never say it enough: “there is no good wind for those who don’t know where they are going”.
5.2.2. Understanding the basics: identify what we already know and what we have yet to find out.
5.2.3. Defining the tasks to be accomplished.
5.2.4. Which technology to adopt?.

5.3. Next steps: do you have an idea about a “secret sauce”?
5.3.1. First phase: find the data(data collection)
5.3.2. Second phase: construct the data(data preparation).
5.3.3. Third phase: go to exploration and modeling 5.3.4. Fourth phase: evaluate and interpret the results (evaluation and interpretation).
