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.

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

Good stuff. Not necessarily a beginner course...configuration of the required software packages requires some work and knowledge, but Mr. Mannino does the best job possible of explaining how that should work in most cases. Installing an Oracle SQL server on the local machine is tricky to get right, but the VirtualBox "Developer Day" package is easier, though requires a little work in Linux...so, I would say no problem for beginners if there is some background in development or multi-OS support. Otherwise, prepare to spend some extra time learning. Was well worth it for me!

Very nice introduction to databases and data warehouses. The lectures are not very engaging, the plus is there are practical assignments for every week, where you learn the most. First you submit your own solution and then you provide feedback to your peers. I like the format of the assignments. What I dislike (giving 4 stars instead of 5) is difficulty in setting up the environment for assignments to complete - it took me longer just to properly install the software needed for assignments 2 and 5 than to work out the assignments. The lectures could be also improved.

quite challenging, high paced lectures. It seems like an easy course because the lectures are quite brief, but make no mistake, there is no repeating of concepts or endless bla bla. To succeed in the assignments one is very likely to watch lectures again. Without any previous knowledge in this subject it is almost impossible to grasp everything by just watching the videos due to the new vocabulary and the information density. The assignments definetly take more time than indicated.

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.

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.

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.

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.

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.

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 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.

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