Chapter 10
Chapter 10 is the shortest chapter yet that explains all sorts of data out there. Data being described as concepts represented by numbers, texts, readings, etc. There is data everywhere at all times. As I am typing this Microsoft is most likely tallying the number of users accessing Word currently. The book uses students taking a test as an example for measuring data determining if the test was hard, or if a student cheated. The book then goes into to the different types of data terminology of data such as datasets, valid data, Metadata, databases, and structured data. Like I said before data is everywhere an example for me using structured data, over the summer my brother and I ran a cornhole league at my house and all the player information was placed inside a spreadsheet to reference at the end of the league, I have made a “database” before and never thought of it as that. Data structures goes into queries and management but from taking Database Managment with SQL I already have a good understanding of the structures. Data policies on social networking sites is mentioned but does not go into much detail, I think that could have been the most important part of this chapter if it talked about how websites and service providers take hold of the data and what they do with it. But I feel a topic like that can takes weeks to cover.
