Great course that strikes a balance between teaching general principles and concepts, and providing hands-on technical skills and practice.\n\nThe lessons are well designed and clearly conveyed.

I like the breadth of coverage of this class. Each of the exercise is a gem in that I get to learn something new also. I would highly recommend this even to experience practitioner also.

Excellent course content and lecture, however, the homework design is not so friendly for students.
First, instructions are not clear. I spent a lot of time in figuring out the real meaning behind each problem. Second, the judge system is not so rigorous. Though trying best on homework and not playing tricks are students' responsibility, the judge system is just too weak to survive those hackings.
Thank you all for your efforts.

Overall a good course, with teachings bit into very manageable lengths of time. My biggest grievance is that your submission has to be in encoded in a particular format (utf-8) if memory serves. So you may have to resave your .txt files if you try to do all the programming on a windows laptop. This may be obvious to some, but it took me a little to figure out.

I feel that there should be more assignments to make the course interesting. The last part just briefly explained about different database types but it also focused two lectures on Pig. There could be an assignment to make the lectures more meaningful or perhaps, a quiz. Otherwise, last week is too much information to grasp at once.

There are some inconsistencies in the course or the arrangement of the videos, maybe due to technical problems.
For improvement I would really wish to have some substantial results, especially in the last week of the course. That is, I would prefer to discuss at least something in depth rather than everything broadly.

This is a great introduction. I would give it a higher scoring but was frustrated with one of the labs have issues in the grader and even after completion of the course its not clear what was wrong: the instructions, the solution data set, the input data set. Other then that enjoyed the content.

The theory and relational algebra is a little heavy for me (I am very much a practitioner). That said, Prof Howe is *excellent* in is presentation. Very clear and easy to follow. Sometimes beats a dead horse (Map Reduce) and as a result, you definitely know what he's getting after!

The lecturer is very, very knowledgable and seems to explain the landscape of topics both from a grand perspective and deep knowledge.
Though there are a wide variety of programming exercise,I would prefer some more in-depth assignments (as is usually the case with me and Coursera).

The contents of the course were good enough. The assignments, though simple required some work in terms of understanding the kind of data that you are dealing with, which is important. Although, a lot of content has been covered, it was arranged in a logical manner.

The course is good. It definitely gives a broad overview of the topics. It's presented in an interesting manner and I would definitely go in-depth about these topics. Although, it would have been more helpful had there been more graded quizzes and assignments.

The power-point used has a lot of mistakes corrected live by the speaker.
The speaker speech is sometime slow and not precise, it probably has been recorded only once.
Apart from that the content covers the subject and the assignments are relevant and fun.

The course gives a good introduction into handling large amounts of data, the problems it poses, and an overview of the available solutions. Towards the end of the course, it started to feel a bit less polished and more rushed, though

It gives good information, but frankly covers way too many tools at the end, and the explanations are good but somewhat rushed. Some parts were a little boring, as no immediate practical use seemed on the horizon.

Very broad and instructive course with a good level of theory, many practical examples. Good teaching.
Some nice assignments but a lake of assignement for the 4th week
I recommand this course

Well structured and nice overview of data manipulation. But the assignments should really be updated in order to use python 3.x instead of 2.7, which is not maintained anymore...

It's pretty tough in assignments especially when there are mistakes in the given description, but I do learn the basic concepts of relational algorithm and MapReduce from them.

Definitely need some background in R or Python and the lectures are a bit old. Seem to be from around 2013 when this first came out but most of the info is still relevant.

Its pretty decent. I liked the assignments. However there were some typos in the lecture slides and also the grader output is not very friendly.

Very good course, but lectures could be more tuned onto the home assignments. A lot of independent work for me at least. Teacher is very good.

Course gives you good overview on different important data science technologies. Hands on labs are important to get the grip on concepts.

Last week of the course is too much information and without any assignments it kind of doesn't make much sense and it doesn't stick.

It is a comprehensive course for learning quite up-to-date technology and concept.
