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.

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.

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.

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.

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.

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.

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.

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5, is that (1) the integration software was hard to install and get working correctly and (2) the course materials are out of date.

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.

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

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.

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.

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.

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.

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.

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.

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.

Great introduction to DW concepts! Assignments are a little tedious and quizzes ask trivia questions sometimes but overall a solid syllabus.

Good course, good explanations.

The assignments were good and instructive, but too many with respect to the length of the course.

Very Well Explained and Guided Course. Pivot4j and web pivot tables have undergone some changes so an update might be required.

Time defined for the graded exercises is not what is actually required. other than that, good course for basic knowledge

Pretty good course. Though course material could be updated and installation of applications was incredibly problematic

Good introductory course. It is suitable for business analysts and folks getting started on their analytics journey.

Some very difficult exercises and the instruction was sometimes too abstract, but overall I feel I learned a lot.
