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.

Extremely useful and practical course. Will give you a thorough understanding of how Data Warehouses are built and Integration platforms operate. Installation of certain tools as required as a part of this course might feel frustrating after a point but it's still worth doing it. One of toughest courses that I have undertaken so far in Coursera. Highly recommended if you are in the right domain with some level of prior (basic) knowledge of databases.

Thank you for this well structured course. Exercises and tutorials are very useful to complement lectures and help increase our skills in the domain.
Tools deployment and connection (Oracle database on Virtual box and pentaho data integration) was a nightmare.
It would be great if you package all the tools needed for a given course into a predefined virtual machine image ready to be downloaded from the course.

Overall - great course giving possibility to learn working on tools such as Pivot4J and Pentaho Data Integration. While I am more interested in Business Analyst approach - it certainly gives meaningful background to data warehouse concepts and data quality. Biggest disadvantage is in my opinion module 5 with rather difficult and unclear assignment. I wish instructions were more precise and whole assignment more analogical to presented examples.

Course is really good and one of its kind, however, there is too much focus on specific tools. In some assignments familiarity with Pentaho is more important than the skills required to solve the problem. As for me I was unable to install Pentaho and had to look for alternatives. Let the course be more problem-centric and ease the focus on using Pentaho as it is not an optimal tool for many.

I enjoyed the first two courses. However, I would have liked to continue but as a Mac-only guy do not have access to an Oracle database, which seems to be a requirement for the assessments and the case study.
The first two courses went well on MySQL, so I'm afraid I have to leave here.
Thanks and bye. If the MySQL option gets added, I'll be back.

Content wise a very good and useful course. But the technical support on the installation and use of the software needed to complete the course is very limited, and the manuals are not up to date, as they refer to older versions of the proposed software. Particularly the Pentaho Data Integration software was a severe test for my peace of mind.
By Kira H•
The instructions for installing the software are not very intuitive and can be very frustrating at times, so make sure to allot additional time getting it installed. The assignment time listed is FAR less than the amount of time to complete the assignment, again, make sure to allot additional time for completing the assignments.
This course demands many software installations. I spent multiple days to have it working. Today, many software are in the cloud and we don't need to handle it. For this class, t would be nice to have access to a cloud platform where everything is already installed, data loaded, and we can focus in practicing pentahoo etls.
By Denis M•
i would give it a 5-star but again the software used in this course/specialization is just ridiculously demanding task. However, concepts in this course are very interesting and I think I learned a lot. Be aware that there is no support from anybody besides peers who most of the times care only about passing.
By Norbert v W•
I like the course, and I learn a lot (having plenty of experience already). However, the assignments take far more time than the quoted 30 minutes, and a lot of time is spent installing and getting open-source tools to work - which I would have rather spent on actually hands on work on the subject-matter.
By William J•
The peer review should be more standardized. There is dramatically inconsistent grading where accurate submissions are failed without warrant causing frustration instead of continued learning. The actual course content is five stars for me. Just the peer review needs cleaning up in my opinion.

A good course, but the learning curve in the middle shoots up so the hill is quite steep to climb. Some typos here and there in documentation, but overall a great course that really challenges you to think hard.
By Zafir S•
Great course overall! Some of the assignments were quite challenging, and it would have been more beneficial to have some guided tutorial videos to assist with some key concepts that weren't previously taught.
By Godswill E•
I enjoyed this course. I learnt a lot. My main difficulties were in navigating the installation of the softwares. I think a lot more has to be done to make the software navigation process a lot easier.
By Justin K•
Great course! The only issue, and the reason for 4 starts instead of 5, is that (1) the integration software was hard to install and get working correctly and (2) the course materials are out of date.
By Matthew P L•
Excellent instructor, content and application of tools. Written instructions can be over-wordy on unimportant instruction and confusing, but so is the nature of the state of data warehousing.
By Manolis M•
The course was very good but it felt a little rushed in the middle. There should be some more examples and explanation In the Data Warehouse design section. Overall great quality of material
By Hadrien D•
Solid class overall, however video lectures do not provide enough background info to complete some of the assignments. Expect to spend much more time than the estimated 30 mins to complete.
By André G L•
A great starting course for the subject of Data Warehouse, I was already practicing on the career and it was valuable to me to strenghten my core and learn new things along the way.
By Mauricio Q•
I think this course is great, however weeks 2 and 3 should be restructured to ensure students acknowledge topics properly. I had a bad time solving those week's asignments.
By Emilio M N G•
Pretty nice course, although installation and pre-requisites could use a higher note before installing since there would be a couple of tries before getting them working.
By Kevin Y•
I prefer the focus on "getting your hands dirty". But I must say, the tutorial's are maybe a bit hard to understand for someone completely new to this topic.
By Salil T•
I love open source tools description. It is really good designed course to refresh your basic. Good job from instructor side to make this course enjoyable.
By Talha T•
The course could be less-detailed. Besides open source ETL tools, other big players (e.g. Informatica, SAP DI, etc.) should be mentioned as well.
By Claudio V•
Good course, good explanations.
The assignments were good and instructive, but too many with respect to the length of the course.
