Boring lectures but she really cares for her students and she is happy to help with anything in her office hours you don't understand.

Prof. Chen knows her stuff but is not good at teaching it. She is very difficult to understand and her grading criteria is not clear at all.

Dr. Chen has a little bit of an accent (very minimal) but she explains database administration so well and when I didn't understand a concept, she did a superb job explaining it. She is extremely kind and she is very easy to access for help outside of class. One of the best professors I've ever taken. Take her for this class! She is the best!!!

Dr. Chen is pretty good. Her lectures were really boring, and she has a hard time answering questions properly. Besides that, the tests and homework are really hard, and the homework takes forever. Group projects are easy.  The pace and amount of homework can become overwhelming. Overall the material is extremely interesting if you put the work in.

Dr. Chen really cares about her students a lot. She's very helpful and kind during office hours and loves when you come to them. The material she teaches is incredibly dry and you will need to put in effort outside of class to succeed. Overall, not the hardest class, but definitely not the easiest.

Heavy accent and hard to understand at some points. Group projects and very difficult tests

Dr. Chen knows almost everything about Database Administration but has a tough time explaining it to students. It's a little hard to understand her, but once you get over that the content is pretty easy to pick up on. She is available outside of class to answer questions (especially through slack which she'll answer pretty much 24/7)

Lectures are very difficult to listen to (hard to understand, boring). She makes herself available and will gladly help you with anything. Watch Youtube videos on SQL and ERD and read outside material so you're caught up. You gain genuine knowledge that you will use in the workforce, so make sure to retain information as you learn it.

She's a decent instructor. Her lectures are VERY dry, but she covers all the content. Her multiple choice exams are quite difficult, but the written and coding portions are fine. Group project isn't bad. She is super nice and will help you if you ask. Only complaint is that grades take a long time to be returned.
