This chapter helped me realize that information systems are less about technology itself and more about how humans make sense of what they collect. I learned that a database isn’t just a storage space—it’s a structured system where fields capture small details, records tell complete stories, and queries act like questions we ask the data. What stood out most to me was the data-to-wisdom model. Seeing how raw numbers can turn into understanding and then into informed decisions made me think differently about everyday data, like grades, habits, or online activity. Overall, this chapter shifted my perspective from simply “using technology” to understanding how information is shaped, interpreted, and used intentionally.
