thinking1dev1person's honest review, Young-han Kim's Practical Database - Basic Course course

The basic course is finished. What I found a bit difficult were subqueries, transactions, and adding new content to the event types in Union Problem 3. + I can also feel from the lectures how important indexes are (there seems to be a lot of content in the index section haha). Also, I have a question. I thought that the 'Data Integrity Section' could potentially be included in the introductory course, since there are problems involving setting foreign key constraints during creation, modification, and deletion. I'm curious about the reason for its current placement. + Also, thank you for working so hard to create these lectures.
