Hi , I'm struggling with Quiz of the DB4 - Relational Algebra mini course. I'm fine working out how to query, but actually writing it down in that silly RA language is getting me down. Can someone please help me. I don't really care about understanding what's going on there, I'm doing this as part of a scholarship thing and no one at this company even knows what the heck Relational Algebra is. I'm not even studying programming or anything with Databases, so I'm just sick of struggling. https://lagunita.stanford.edu/courses/DB/RA/SelfPaced/courseware/ch-relational_algebra/seq-quiz-ra/ #2
