- Don"t know why the deadlines were moved all the time. Really don"t want to work myself to death over a dealine that is moved at will... Everything else worked well.» (Rather well)
- The handling of the assignments in this course is outstanding, and in my opinion this should be an example for the rest of Chalmers (or at least for some courses)» (Very well)
- The lab supervisors were very dedicated. They took the time to sit down a while with the students and reason with them. The web page contains just the right amount of resources.» (Very well)

- almost a surplus of exercise sessions» (Very good)
- The climate at tutorials were great. We came without prestige. Everyone asked a lot of good questions and interacted with each other.» (Very good)
- Well, when skipping another class to go and ask questions at the lab session, it"s of course annoying if there still are several people before you on the list by lunch... But the assistances did a great job!! By end of lunch they had helped all of us. » (Very good)

Poor»2 4%
Fair»0 0%
Adequate»11 22%
Good»21 42%
Excellent»16 32%

Genomsnitt: 3.98

- The concepts are quite old. Course should be called "Relational databases".» (Poor)
- The course was a bit too easy, even for a starters course.» (Adequate)
- An interesting course, well executed.» (Good)
- Excellent course all-around» (Excellent)
- Labs were very important in my opinion.» (Excellent)

15. What should definitely be preserved to next year?

- lab structure»
- Keep Nick Smallbone as an assistant. He does a great job.»
- Almost everything»
- Nick Smallbone was great. Good lectures with Graham.»
- The assignment is great! Not too big, not too small. It was also good that it was in 4 tasks this year. It would have been harder to keep up with 3 tasks.»
- All the assignments and the course literature.»

16. What should definitely be changed to next year?

- nothing to point out»
- The lab assignment was poorly specified. Labs were rejected with references to parts that hadn"t been specified in the assignment. »
- exercise lectures should be more interactive»
- Database software. The sqlplus commandline for some reason worked 10% of the times I tried using it. The web interface would only push changes if you logged out and logged back in, and oracle seems to use a load of syntax no-one else uses (that"s just my oppition though). Better use postgre, or mysql instead, I believe they are better. Would also be nice to hear about things like CouchDB, Cassandra, etc. Also it would have been much nicer if a computer was used instead of a blackboard during the lectures. Both for slides and showing concepts in the database.»
- The XML part. Maybe you can cut out the fourth lab and replace it with a small XML lab. As it is now, the course gives me a conceptual understanding of XML, but I can"t really do much on my own.»
- More tutors during the laboration hours. It was also hard getting good help when neither Nick or Graham was there.»
- Nothing»
- The exercise time can be set in the afternoon or later in the morning.»
- The exam time was too limited. Perhaps fewer questions on the exam.»
- Bring up the subject of common database security issues, like SQL injection attacks for example. With so many databases used within systems exposed to the internet, this issue is important!»

17. Additional comments

- I have done three years in Chalmers now and I think this course is one of the best ones I have attended. Great work Graham, Thank you for a great course»
- Good stuff»
- The tutorials came a bit overlooked, because of lack of time. They were good though for exam studies and the sessions were a good opportunity to ask questions. Maybe the solutions for Tutorial 5, on the web page, should be looked over.»
- The course is good, even for me who does not learn Java before. But I hope more guidance for using Java, like changing the path, and setting the variabilities.Because my partner who has used Java before also forgot how to start using it.»
- Its difficult to read a very time-consuming course, router and switch on Lindholmen and at the same time read database on Johanneberg.»
- Sometimes you feel that some courses lose track of their purpose, that they get too deeply involved with details instead of that which should be the essence of the course. Not this course though, it does a good job of delivering a healthy amount of database knowledge and insight. I would recommend it.»
