Intro
I was working for my first commercial project, my mentor ask me Do you know what’s the scrum and agile?. It’s like invisible elephant stays at room. Everyone is talking about that, but I don’t know details about it. Attended first stand up meeting, filed the first ticket(story) and finished the little stars. I finally touch something there.

Database 如何存取資料
