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.

This was a great course, but the software installation steps took a lot of my time for the assignments

It's a great course, with quality content. But I would like to see more practice videos for the tools.

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.

This course has plenty room for improvement. On one hand, it provides a good understanding of the different data warehousing architectures and design principles, an essential foundation to anyone interested in the field. The material on data integration is also excellent, along with the associated assignment. On the other hand, the peer-graded assignment on data warehousing design is very demanding and isn't clearly described from the lectures and practice problems what the students ought to do to get a perfect grade. Installing the software and getting it to work is also a skill on its own, but it truly is something that a professional will encounter in their work!

Pros: Information is perfect for anyone looking at Business Intelligence as a career field, or already in the career field itself. I found the first week to challenge my on-the-job knowledge of a fuller set of concepts and general terminology.
Cons: The wording on the quiz questions, in some cases, seems much different than the PPT slides and the instructor's language. UPDATE: The wording is a significant challenge, even when advancing into the more complex topics. I have had many differences of opinions on the solutions based on wording in the requirements.
