- Probably the best lectures I"ve been to. The slides to the lectures were superb - they were very usefulwhen studying for the exam, or when I missed a lecture and had to catch up on my own.» (Very good)

- nog för att ställa sig mitt under föreläsningen är jobbigt men det är behövligt. bra sätt att inte somna på» (Very good)
- keep up the good work :)» (Very good)
- The lecturer (Niklas) might in my opinion been the most outstanding element of the course (in a poitive way that is...) The layout of the lectures along with the charismatic teaching style at least suited me well. May mostly be because I was prevented from falling asleep during lectures though...» (Very good)

- Little tricky. Java project and assignments should have some weightage otherwise it is useless.» (To some extent)
- Only SQL» (To some extent)
- Except I would have liked to have the order of the assignments reversed. Working with the same project throughout the course is good but it would have been easier for me to start with JDBC, continue with queries and tables and then finish off with the designphase when I had more knowledge of what possibilities there are when implementing a database.» (Yes, very relevant)
- I noticed that many students have done the 1st part not perfectly correct, and had problems understanding Normal forms. Yet they have passed the 1st part as accepted.» (Yes, very relevant)

- A bit tricky... maybe split it? And adding another submission in the middle of the assigment 2 time... så that people actually starts with it in time =)» (OK)
- It was okay but I would have pefered if it was split up in two parts or something because it was very heavy and we sat man hours working with it.» (OK)
- I"d like to say we did it in one afternoon, but that would be an utter lie.» (Good)
- I think it could be narrowed down a little bit.» (Good)
- It"s big but i guess i can"t complain» (Good)
- Lot of code and kind of messy code to write.» (Good)
- Translating the schema into Tables was the good part, inserting data was a waste of time.» (Good)
- I didn"t find that it was as hectic as everyone kept saying it would be. It did take quite a while until it was accepted though (final week, I think) but it felt like we had it under control.» (Good)
- Too heavy» (Very good)
- A most relevant task, though very time-consuming. If we hadn"t started on task 2 prior to deadline of task 1 we might have run into some problem here.» (Very good)
- It took a lot of time, as promised. Since we were aware of this at an early stage, this was not a problem to me. » (Very good)
- challenging» (Very good)
- Took much time, especiallt the triggers when not knowing the exact syntax. Would be nice to go through that in lectures just to give students a start.» (Very good)

- too easy» (OK)
- But it should be a question on the exam about jdbc and not about relational algebra or transactions» (Good)
- Less interesting than the other two (due to the simplicity of the final task) but it"s good to see the whole thing work.» (Good)
- Wraps everything up into a finished product, which is very satisfying. It was nice to have somthing less intense at the end of the course. » (Very good)

- The return comments was great but the time it took for an assignment to be corrected was very bad.» (OK)
- Took time to get returns» (OK)
- The delay from sending in and getting a return, aswell as finding new errors every time submitted (aswell as some errors we found, after being accepted that was crucial for the next part). They did a good job, but they would have needed more correctors.» (OK)
- Some parts was not that relevant but overall good.» (Good)
- sometimes, I felt I needed more explanations.» (Good)
- Sometimes we saw and corrected stuff that the people who corrected our assignments missed, but I guess that"s natural since there was a lot of text with many small, small details to miss. Good overall.» (Good)
- First assignment took some time due to errors not found in the first hand in. No biggie though. Quick responces to hand ins.» (Good)

- Alldeles för få kurs-assistenter... man kunde som mest få hjälp 1 gång / övningstillfälle så det var nästan inte värt att åka in till skolan för det.» (OK)
- did not attend many» (OK)
- Supervision sessions? Labhandledning? In that case too few supervisors. People needed much help.» (OK)
- We had problems with one of our triggers that the supervisor couldn"t help us with during supervision» (OK) (den här kommentaren har blivit redigerad i efterhand)
