In this unit, we looked at how data can turn into something useful. We talked about the DIKW pyramid (Data, Information, Knowledge, Wisdom) and how we use it every day without realizing. I also looked into how relational databases work, basically how systems like IMDb or SIMON connect different tables (like students, classes, grades.) using keys so everything stays organized.

The big picture I took away from this is; lesson is the data to wisdom idea. It's simple but it makes sense, data is just random number like 9, but it doesn't mean anything until you give it context. Like a 9/10 movie rating. Once you have that, you have the wisdom to decide if you want to watch that movie or not. I also realized I'm basically querying databases constantly. For instance, every time I search for a song on Spotify or look up a movie on IMDb, I'm using a relational database. I realize that information is like fuel for everything we do now.
