- And more. The exam was to hard, it did not reflect the goals, and to lite time, i always have spare time on my exams, but this time i didn´,t have time to finish..» (To some extent)
- Why didn"t anyone tell me that we could have AN A4-Paper with own writings on it for the exam!?! I attended to every lectures, you could have mentioned that Graham! If I would have known it I would have passed this course..» (To some extent)
- Many points on the exam was lost due to lack of time. That does not reflect how well you understand the course.» (To some extent)
- But the tasks on the exam required too much "unnecesary" work to evaluate whether or not u have understood a particular course-part. As a result i think most people that took the exam felt that they didnt have time to even finish all tasks. In the room i took the exam in the majority of the students turned in their exams when they time was up.» (Yes, definitely)
- i don"t think four hours was enough time for the exam. i had the pen constantly to the paper and still i had one question left at the end.» (Yes, definitely)
- I liked the exam. I thought it tested all parts of the syllabus. I especially liked the question about the ER-diagram, to find what was wrong, I thought that was a really good way of testing the understanding for ER-diagrams.» (Yes, definitely)
- The exam was to way too extensive, there was simply no time to answer all questions.» (I don"t know/have not been examined yet)
- Because it overlaps with another course I plan to take the exam next quarter» (I don"t know/have not been examined yet)
- i don"t understand this question» (I don"t know/have not been examined yet)

- Way to few course assistants» (Small extent)
- Graham (Lectures and labs): Great!! Torbjörn (Tutorials and labs): small extent, he doesn"t seem very enthusiastic about the subject. Phu (Tutorials and labs): small extent, more effort spent on communication issues than on understanding the topic/problem» (Some extent)
- Much of the time spent on the labs was waiting in line to ask a question. Other students can answer some things. There"s a lot of people doing this course that you don"t know, in previous courses most students have known eachother and so it"s been easy helping eachother when stuck. Don"t know how how well all the other students know eachother but my guess is that people will ask a teacher first if they don"t know eachother. Conclusion: need more teachers during the labs.» (Some extent)
- ... can"t answer questions without checking the textbook or lecture notes, he is always pointing out where to find the reference. ... did acctully never help us, only point where to look. He pointed out where to look even if we had that pdf open on the screen at the same page.» (Large extent) (den här kommentaren har blivit redigerad i efterhand)

- it was great for the ER-part. Didn"t read more» (Small extent)
- The book was not so good. » (Small extent)
- The course literature is hard to understand, i can recommend Thomas Connelly & Carolyn Begg : Database systems - a Practical Approach to design, implementation and management» (Small extent)
- The book was very bad, the examples were nonintreging, poorly done. » (Small extent)
- This book is by far the worse course literature i have ever had in 2½, years as a student in Chalmers. The example are so simple that it"s no idea to look at them. It would help sometimes to get more advanced examples. Even so, not many of the example were of any help since we practised on Oracle and the syntax differs from the one in the course book. Change book, get one wich is oracle friendly instead..» (Small extent)
- Barely looked in the course book. Did most studying with other material, wikipedia.» (Small extent)
- Didnt buy the book, never even seen it. The lectures notes were great thou.» (Some extent)

- The fact that there were no way to signup for a final evaluation of the labassigment, except a "hidden" list past around on a particular lecture, was not good at all. Would be better if the DB-course would use the studentportal-signup-features for that, as most courses do.» (Rather badly)
- Please get a person at the lab who actually knows about databases.» (Rather badly) (den här kommentaren har blivit redigerad i efterhand)
- Though I still can"t see why IT-courses don"t use the studentportalen like all other courses» (Rather well)
- The slides was very good!» (Rather well)

Genomsnitt: 3.32

- Sometimes we could not log in. We could not resubmit files and it was very rigid when the deadline had been passed. Why not use the system in the StudentPortal instead? The Oracle system did not work at all. First we did not have enough priviliges, and no one answered our e-mails or our phone calls. Thus we spent a long time not being able to do the assignment. Then, finally 24 hours before deadline, we got a new account... Thus we didn"t have enough time to do the assignment. On the final task the database collapsed, and before that it was slow to respond and behaved strangely. I ended up installing an Oracle database on my own computer to be able to work. Oracle doesn"t support auto increment and I don"t like that. I want to use unique numbers for all my relations, not to use strings for keys, thus I much prefer MySQL.» (Very badly)
- Only problem here is that my grader didnt really correct my task2 of the labassignment, he just accepted it even thou it wasnt really done. Eventually i got it done ofcourse since it was needed for task3.» (Rather well)
- everyhing was fine but at the second lab we recieved the response from karfunkel one day before the final deadline and that was a little short.» (Rather well)
- User friendlyness» (Rather well)
- Some trouble before you got used to it but after that it worked fine.» (Rather well)

- We could sit 2 hours during laboration time without getting any help. » (Very poor)
- ... seemed to know less about databases than us students. Also, queues to ask questions were really long.» (Very poor) (den här kommentaren har blivit redigerad i efterhand)
- It was difficult to get good answers turing the lab sessions since the tutors had not used oracle. » (Rather poor)
- see q7» (Rather poor)
- Many people attending to the lab"s, hard to get help from one teacher.» (Rather poor)
- As stated earlier» (Rather poor)
- Sometimes there were a little few teachers in the lab-sessions. The teacher who was there seemed to be very stressed but helped us as good as he could.» (Rather poor)
- Hard to get help on labs sometimes, much people..» (Rather good)
- Graham is awesome, I"d glady read another Graham-course. » (Very good) (den här kommentaren har blivit redigerad i efterhand)

- maybe add a lab on XML, thats the only thing i miss about the course.» (Good)
- except for the exam and the book» (Good)
- The lecturer dried his best in preparing the coures. That"s the same case for my course assistant.» (Good)
- bad lab tutor and bad possibility to get help are the things that prevents this course from scoring excellent.» (Good)

16. What should definitely be preserved to next year?

- The examples and assignments. »
- The three sessions, lectures, tutorials and labs is a very good way to involve students»
- Inget!»
- One big assigment with many parts, a good way of evaluating all parts of database-construction.»
- the labs were good for the understanding of the course»
- Good to have a programming assignment.»
- Almost everything =)»
- The three-staged lab! But with more tutors at lab classes.»
- The exam style»
- The web site and lecture notes»
- The lab-sessions is good for better understanding.»

17. What should definitely be changed to next year?

- Lecture notes should be able to download before the actual lecture.»
- The databse server»
- Torbjorn. The lectures where we solve questions without getting any help.»
- Language ability among the instructors for tutorials and labs.»
- tutorial execises wasn"t that good.»
- The number of assistants.. Have to more help available during laborationtime»
- Gör om hela kursen från början.»
- Add a signup-system for lab-evaluations. Make an exam that covers fewer points and less work but checks in same way if the students know the course.»
- It took a very long time until we got our return on the lab»
- Shorter exam!! training sessions in smaller groups which focus on the turtorial material. »
- maybe add a lab on XML, thats the only thing i miss about the course.»
- Since MySQL is the most widely used DBMS on the web (at least by students using "cheaper" web hotels, I guess) you should maybe consider to change from Oracle to MySQL.»
- The part about XML... remove it or give it more time. »
- The book, more diffrent kinds of examples it gets a bit boring with course, givencourse, teacher etc, i believe more examples would be useful»
- The Oracle database The Fire system»
- As a course, it seems to be fine»
- change the laboratory exercises, make them harder»
- Please do notoverbook us by having lectures at the same time as our other course. It happened both on thursdays and on fridays, but happily it didn"t cause us to much problems.»
- The Exam was way to big and hard to grasp.. I stressed through the whole exam and made tons of errors becouse of that. »
- The computer rooms for the labs were too full and the lines for help too long.»
- More and better teachers for the lab- and excercise sessions. Some teachers were good and some were not.»
- type of questions on exam»
- Labassistant» (den här kommentaren har blivit redigerad i efterhand)

18. Additional comments

- Nice course.»
- The teacher doesnt always seem to know what he is talking about»
- I did not think that the exam would be as difficult as it was. There were actually too many questions to answer for 4 hours.»
- Jag tycker kursen var totalt värdelös, innan kursen började såg jag fram emot den, men det ändrades snabbt. *Labbsalarna var alltid överfulla, luften var helt värdelös och väldigt svårt att få hjälp under dessa lektioner *"Programming Assignment" som vi fick hade en fullständigt katastrofalt dålig beskrivning, vissa tekniska krav som var obligatoriska var väldigt svåra att tolka och framgick väldigt dåligt ur texten. *Jag tycker även att inlämningsuppgiften fick alldeles för stor fokus, alternativt felaktig balans mellan den och tentamen, om ändå allt som var relaterat till inlämningsuppgiften kom med på tentamen, varför ska då inlämningsuppgiften vara obligatorisk? *Föreläsningarna stämde inte överens med tentamen, det borde föreläsas mer i tekniska detaljer/implementationer, föreläsningarna var alldeles för abstrakta. *Min personliga åsikt är att tentamen också var en ren katastrof. Jag satt tiden ut, och hann ändå inte med alla uppgifter, detta har ALDRIG nånsin hänt mig förut, salen jag satt i och skrev tentan var det max 2-3 personer som gick innan tiden var slut, så uppenbarligen var det inte bara jag som hade tidsbrist. Jag skulle kunna fortsätta skriva mycket mycket mer, men avslutar bara med att säga att detta var den sämsta kursen jag har läst.»
- the lab supervisors could be more, it took a very long time to get help sometimes»
- On the other hand, if many students already are using MySQL (often together with php), and probably sooner or later will get in touch with MSSQL (probably together with ASP.NET), it could be good to keep using Oracle to achieve a wider perspective...?»
- We often had serious troubles with the database due to database overload!!»
- A great course (if the exam went well ,))»
- A good course. It"s my pity to miss the exam.»
