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 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.

•Really short lessons, and usually half of lesson is spent on introduction and talking about what will be in the lesson. Nevertheless, course is focused on theory, rather than the practice. I think it should be more detailed and with more practical assignments.
par Linda S
•Well organized lectures but the documentation is full of errors. This in combination with the lack of response on the a lack of responsiveness on the forums might make this class frustrating for some.
par Tom C
•This course needs a cleanup of loose ends on some of the assignments. Some assignment requirements are very ambiguous and in some cases the solutions are not matching the requirements of what was due.

•Real world data warehouse integrations are more complex than just inner joining the tables to drop those rows not found in the original tables. i wish more complex scenarios are covered.
par Shalmoli N
•Assignments are very good, in fact excellent, but the material could be a bit more descriptive. And the practice exercise of assignment 5 had lots of discrepancy with the actual
par Andy O
•Some good parts on data integration but the key sections on DW design and in particular the assignment are really poorly written.
par Rohan L
•Needs serious updates. A lot of good information, but assignments are thrown together, and instructions are often not clear.
par Bruno A S I
•It's a good course but it could improve the explanations provided in giving more detail and examples. Give deeper examples!!
par hatem e
•An introductory course, gives the very basics on the subject. Lacks in material and (available) references.
par Odile M
•Missing course material about how calculating fact table size ans sparsity
par Ravi
•Good for Beginners to go for.

•This course was full of issues related to the installation and use of Pentaho Pivot 4J and Data Integration. The professor's presence is resolving these issues was practically nonexistent. Coursera needs to do a much better job at insuring that their professors are offering a quality course and living up to the expectations of the students. In the case of this course and the professor, they failed miserably. In addition, it is practically impossible to get support from Coursera when an issue exists and in most cases when contact is made, the assistance is minimal. It is a shame as the platform is nicely designed and the course topics are very interesting. If you are considering taking this course, be forewarned that the majority of the support of problems/issues come from the community, not the Professor or Coursera. In addition, you are required to grade the assignments of your fellow students. This is not done by the professor.
par Jacob G
•Content is lacking and final assignment was a nightmare; difficult to install multiple pieces of software only for a tedious assignment, that ended up not working the way they were supposed to leading to me not fully completing the work. Course videos are mostly wasted time - first introduce the topics that will be discussed, summarize points you should get from the lesson, followed by 2-5 minutes of actual content, then a summary of the minuscule amount of info you just heard.
Must not be a popular course, because peer grading often took a while, and there often were not other submissions for me to grade. Needed to go to discussion which solely consists of old posts from people needing grades
par Sylvain L
•Not enough implication from the instructors in the course. Students are left alone with the material, without any answers to there questions on the course.
Peer review process subject to personal interpretation and leading to frustration for the students.
That's quite unfortunate as this provides a bad experience whereas the course might have been good without that.
