學生對 科罗拉多大学系统 提供的 数据仓库的概念、设计与数据整合 的評價和反饋

The torture of having to identify which of the many combinations of Pentaho, Java and some freeware plugin actually works in the end has completely ruined this experience. I don't care if SOMEWHERE in the notes there is info I should install Version 5.0.2.3 instead of 5.0.whatever, this is just plain laziness in the course design by picking software which might have worked in the past and then not updating the instructions while pocketing the student's money for years to come. I have about had it with spending my nights installing and re-installing this junk of software nobody uses anyways in a real business setting only to advance in this class.

Personally I don't recommend this course. I really need to learn data warehousing for my job and I have no problem with learning by doing. This course gave me basics, but the learning was very stiff. I think it's just to theoretical here.

The quality of assignments is awful

Disgracefully outdated course that does not match with the technology that it claims to use -- dont bother with this one

Pentaho does not work, hence I was not able to complete week 2 assignment and the course.

No guidance from instructors, and the assignments have nothing to do with the lectures. If I could get a refund, I would quit and get my money back. Not worth the frustration.

Good learning for Data integration and ETL learning. How data from source to target table transform over the business requirement to be ready for processing

A very good course. It is challenging, especially the assignment in week 3, but extremely rewarding. Thanks to Coursera and the University of Colorado for creating this course. Really good to get an understanding of enterprise level data warehouses.

Overall a great course mixing concepts, technical skills and self learning very well. I'd recommend this course for anyone who is looking to learn about building data warehouse from scratch with minimal starting knowledge.

Again, professor Michael Mannino presents a very well prepared course that achieves optimal results in limited time. This course provides the background and basic skills necessary understand and work with Data Warehouses.

Excellent course in the way of preparation to be a Expert in Business Intelligence and Data Warehouses.

100 % recommended!

I've learned lots from this course. I highly recommend it if you want to learn the concepts behind data warehouses.

good material but should update some videos since program versions have changed.

5 stars for content and assignments; 2 for peer-reviewed grading

The content in this course is very good. You'll learn some good concrete skills, while completing some challenging assignments.

The peer reviewed assignments are problematic. Cheating is rampant. Your peers will often turn in empty assignments, I assume so they can get access to the answer file. I have had to review assignments that were blatantly plagiarizing the answer file. Another peer even plagiarized my own work as his. I have flagged multiple submissions as plagiarism, but I don't think Coursera does much of anything with these flagged submissions, since cheating is so commonplace throughout the platform. I just tell myself that I'm here for the learning; I can't stop others from stealing my own work. Seriously, who takes a MOOC just to cheat??

I suppose the integrity and honesty problems I mention above are more problems pertaining to the Coursera platform as a whole, but having your own work plagiarized definitely affects your experience and perception of a class. Furthermore, it should be up to the course designers to develop assignments that work in spite of Coursera's problems.

Despite all this, I will be continuing with the course series, as this is fascinating stuff.

The course content is what saves this course from getting a really low score. I actually learned a lot about data warehousing so I can forgive a lot of the logistical problems that this course has, and these problems are not necessarily problems with this course but may be more widespread among coursera in general. Take this course if you are interested in data warehousing but are willing to be a completely independent learner. The course forums are full of people asking for their assignments to be graded which doesn't make sense because I never had to post anything, and mine were eventually graded. Module 2 has a bug where there are 2 assignments to choose from, but coursera thinks you have to complete both to pass the module.

The assignments are interesting and you will learn a lot if you actually complete them. From doing peer reviews I noticed a lot of people not even doing the assignment and hoping that people will just give them a passing grade. There is also a lot of plagiarism going on because I graded the exact same submission many times.

Aside form the issues above, I learned a lot, and I think it is actually worthwhile to take the course if you are patient and can self-teach.

I love both the theoretical and practical nature of this course. Enough content is provided to ensure a smooth introduction to data warehouses and proficiency in the important concepts of Extraction, transformation and loading. The progression of content across the weeks is excellent and Michael is definitely the best instructor in the subject.

I love this course! Especially with the practice exercises. This course has helped me significantly improve my understanding & the technical skills revolving data warehousing. It would be much better though, if this course has a lot more technical exercises, learning how to utilize essential data warehousing tools efficiently.

I just re-reviewed the 1 week and will re-review it within the day, prior to taking the exam. overall the presentor is very capable and has mastery of the subject which is very very good. I love this course and i hope I could have this re-reviewed once I get to have the paid subscription.

Excellent course, you will learn how to use data warehouse tools, you will gain design experience and have organisational context to work in data warehouse development projects. My experience from this course is you need to be quite dedicated to pass.

great course with hands on practice of the concepts. Getting the tools installed is a little frustrating but once you get past that part there are a lot of good exercises to apply what you are learning.

I liked the quality of lectures. Exceptional meterials to undrstand classic ETL/ELT process in a nutshell. I used this course to get basic knowledge on this thing before an interview.

Great course. It mimics real life case. However, the time required to complete assignments is much more than stated. The assignments are great though, I learned a lot from those.

Very nice class, well thought out and organized. The assignments are interesting and the practice assignments are relevant. Getting hands on on Pentaho was a big plus.

I enjoyed learning this material and found that the Pentaho Kettle hands-on experience was a nice additional to skill set that I can provide my clients.

Good course for starting DW and ETL. Some of the technologies like Pivot4j are old/ irrelevant today. They should be updated with latest technologies
