- Exam: Stupid to have differient levels (3-5) of each question.» (No, not at all)
- Not alone, but with labs: yes» (To some extent)
- Like all programming courses they never fully test you when there is an exam since you ALWAYS can check the right answer in real life. As long as you know the "basic" you can figure out the rest very fast and make it correct, something impossible on a exam. It just mashing info into your head you don"t need and will just forget, sadly. If there is something to be removed, it should be the exam. But its like that for almost every programming course.» (To some extent)
- Absolutely awesome exam, if more courses had exams like that I"d be positively thrilled.» (Yes, definitely)
- examination is designed in a way that"s really hard to cover with in the specified time.» (Yes, definitely)
- I did feel a bit unprepared though, E/R-diagrams and Schema etc. we"ve put a lot of effort into but XML, DTD should get a little more time considering how much these questions are worth on the exam.» (Yes, definitely)

Poor»1 2%
Fair»1 2%
Adequate»6 12%
Good»17 36%
Excellent»22 46%

Genomsnitt: 4.23

- It"s not a course that I would recommend anyone to take.» (Fair)
- Great course as in the field and subject - however too little were included in the course and the standards were too low too.» (Adequate)
- I feel more comfortable as a software engineer since i"ve taken this course.» (Good)
- Great teacher» (Excellent)
- Everybody studing anything IT/programming related should take this course. Its the best I"ve taken so far!» (Excellent)
- I had high expectations since Niklas recieved the pedagogic prize last year and he has not dissapointed me.» (Excellent)
- Great-to-know material presented in a tangible sense » (Excellent)
- Great course!» (Excellent)
- Superb course!» (Excellent)
- This course should be mandatory for all IT-students at least.» (Excellent)

14. What should definitely be preserved to next year?

- Everything»
- The project»
- The teacher, the course and the exam structure»
- Everything, especially Niklas Broberg. »
- The book.»
- The laborations. Gives us students a full insight of the process.»
- Nickolas was a good lecturer, it would have been nicer if he could have given the one of the three tutorials. »
- The course should have a hand in assignment. But it should be expanded.»
- All lectures were excellent. Best lecturer ever + very good slides. Nice to get access to them as well, which means you don"t have to take notes all the time. You get more time to listen and understand. Also all quizes in the slides were very welcome.»
- course format and contents in general»
- The teacher, Google Groups, the excercise breaks (and should be applied for other courses as well)»
- The wonderfull lecture slides. The opportunity to work against Chalmer"s Oracle database.»
- The lab assignments, the teacher.»
- The course responsible and his way of teaching. Skilled and experienced. Knows his way around and can relate facts to the outside world. Doesn"t just read the slides, but can talk freely about correlated matters. Quizes are a great tool to activate the audience! »
- Lab assignments»
- Nothing. The course is quite hard if you are not familiar with SQL and MySQL/Oracle/MsSQL/../MircosoftAccess before... I think there should be another advanced course of Oracle/MySQL with more examples to investigate all tricky places of the both systems. We must not only study Oracle as MySQL is a good open-source/free solution and we can not just throw up it. »
- The structure in how the course and exam were divided into blocks.»
- Everything.»
- The incremental assignment.»
- labbarna var bra»
- the teacher, the labs»
- Everything»
- Teacher.»

15. What should definitely be changed to next year?

- I think it would be preferable to instead of having three levels on the questions on the exam, you should come up with some kind of build up questions instead. I think it was an extra unnecessary stress moment to have to think about choosing level of question. It"s better to have a smaller A level followed somehow with a discussion that qualifies for more points. I think it would be very good if you could hand out the information needed to insert the data in that part of the lab so you don"t have to sit come up with so many names and stuff yourself. You can just give the names and such of the courses without giving up the relation schema.»
- Review the explanation of BCNF and other NF"s as right now they are very hard to understand.»
- Nothing»
- The exam type.»
- If anything more tricks with triggers could be discussed in the lectures. But that might be just me.»
- The A questions on the exam where insanely hard, and the B were much easier, everyone i spoke with after the exam felt the same.. Why would you do that? Me my self didn"t read the B questions until in the end which was a huge misstake.. Probably failed because of that.»
- Exam.»
- Nothing»
- Give a pick at other DBMSs at one of the lab sessions. (other than Oracle). »
- Include more or go deeper - the course was too shallow and contained too little. Also the hand in assignments could be "larger" ie more work.»
- Everything was good enough, but the excersice sessions could be improved (they were not bad though).»
- the way of Exam. its not the normal format and really hard to cover it during the time. even though if a person know everything still he/she is unable to get some good grade. 4 hours for doing this exam is really unrealistic time. this issue must be look into.»
- Perhaps introduce a couple of small assignments or exercises similar to those that will make up the exam to better prepare the students.»
- Access to the database from outside of Chalmers ip-range. While it is possible to access using SSH, it"s rather slow and has negative impact on productivity.»
- More focus on the alternativs (XML)? (In labs and lectures e.g.)»
- better slides, that more clearly explains the theory, not only saying what yo shouldnt do.»
- Nothing»
- The second lab assignment (triggers). It was very hard to figure out what to do and how to do it.»
- Maybe stuff like XML, Xpatch and XQuery received too much coverage. We didn"t get much practice on them, but they still were on the exam (not much though). Maybe there should be some more time to practice them (an extra exercise or sth, or even better a simple submission task), either that or just drop it altogether.»
- Nothing.»
- Gick bara på en övning och kändes inte som det gav något så tycker man borde förbättra dem»
- more prominent oracle PL/SQL resources, clearer info on the differences between SQL and oracle SQL»
- Nothing»
- Don"t recommend the course book.»

16. Additional comments

- Best course so far, really really really good.»
- Mix in some relational algebra and xml in the labs»
- The course prerequisites say in a very strict way that you need to have taken a course in data structures. I find this totally irrelevant for this course. It is a shame because that actually stopped me from taking the course earlier.»
- The exam and the labs seem very seperate. It would seem to me one can be an excellent database designer/creator/implementor - easily doing the labs - and still stumble on the exam questions.»
- Thumbs up! Keep up the good work :)»
- With young teachers such as Niklas students have fun besides learning. He is talent in teach and human behavior. »
- The teacher (Niklas Broberg) was great, he was probably one of the best lecturers I"ve had at CTH, and definitely one of the few who could grab your attention and hold it for the entire lecture. The lectures were light, interesting and very informative. Keep it up! Great success! ^^»
