Today, during my commute, I attended lectures on Database Systems and Discrete Mathematics.

In Database Systems, I listened to the final lecture in the SQL section. Since SQL is something I already use in my professional work, I found this part relatively easy. The only aspect that still feels somewhat confusing is that the DATA format used in actual DBMS environments differs from the one presented in the academic study of SQL.

For Discrete Mathematics, I reviewed the lecture on matrices, even though I had already studied it before. Because I had gone over the textbook in advance yesterday, I was able to understand most of the material much more clearly this time. However, I am still somewhat confused about the concept of row echelon form, so after finishing this post, I plan to review that part again.

As for exercise, today was Pull Day, so I completed pull-overs, pull-ups, the low row, the lat pulldown, and the T-bar row, and then finished the workout with stretching.
