Constraints and Triggers Exercises 2

• Independent work on the Social Network Exercises: (https://lagunita.stanford.edu/courses/DB/Constraints/SelfPaced/courseware/ch-constraints_and_triggers/) You can see Doug’s visualizations of problem statements, but beware — people vary of the ways that they (best) visualize information). But the bigger lesson is that drawing can sometimes help.

Optional for later:

• Do DB11 EXTRA movie database constraint and referential integrity exercises
• Do DB11 Extra Social-Media Triggers Exercises
