Good Explanations of Concepts and Nice Tests. I got a trilling experience in completing the peer Assignments with keen observation and Analyzing of Concepts learned.Thanq for your course very much.

Nice course to describe the traditional data modeling (RDBMS) as well as various semi-structured and un-structured data modeling and management of the systems (Batch and Streaming data processing)

Definitely could have used more hands on practices. The hands on practice examples could've delved deeper into 'how' instead of just giving you the command lines to run. Majority of the times were spent on lectures talking about abstract concepts. While useful, more of that time would've been better spend on hands-on examples.

3.5+ star course. I hope by studying the following courses, contents of this course prove to be more practical.

Reasonably good, but less structured and organized that the first course.
I hope the next one will be better on this aspect.

This was my second course of six. It was so theoretical but at the final exam it required so much exercises. I propose enrich the course with exercises and hands on

The course has a lot of information that is completely useful for BD, I feel that it needs more hand-on exercises. For example, all those BDMS they listed are very useful, but it would have been more practical and fun to teach with an exercise, rather than 50+ slides.

Very interesting but I struggled with some of the content: the level jumps suddenly, and the course lacks some clear examples of application.

Week 6 Peer graded assignment instruction should be more detailed.

The course is great. The final peer-reviewed project is interesting, but very badly designed. The explanations are fairly confusing, and the peer-reviewed format really doesn't fit this assignement, as modeling can be performed in many different ways, that untrained peers might not recognize.

Capstone assignment was disappointing.

Good information overall, but the "peer graded" assignment at the end is poorly designed and seems unnecessarily arbitrary. Not a clear value add over a "final exam" format to justify waiting days for someone to "grade" your work. Instructions for this assignment are poorly written and unclear - for example, completely NOT clear you are asking us to identify a primary key versus stating there is no primary key, etc.

I feel the assignments were a little vague and such assignments should be reviewed by mentors and not just fellow colleagues. Also, the concept on which the questions were based, were not covered that widely.
Additionally, if someone wants to refer to the slides in future they should be able to get the information they want from the slides itself, so they could be made more descriptive.

Hands on practice needs to do a better job

I felt there was very little continuity between each of the 6 weeks of this course. Especially in week 1, where I noticed a significant jump in the level of the content and I found the lectures quite vague and ambiguous. But overall I am satisfied. Looking forward to course 3.

Final assignemet is too hard.

Expecting more hands on experience with big data frameworks like Hadoop or Spark. Instructions of the final assignment is very confusing, you don't actually know what it really want you to do until you go through all the Q&As in the discussion forum, which is really wasting time.

There has been very few on-hands training. It's still very very at an introductory level. At some points it goes very deep, for example with the vectors for a document, but with the rest stay at a very high level. Open an excel sheet can not be considered training ...

Although Content quality was good, the content is too much less and could have been easily integrated to first course or other course in specialisation.
Secondly Quiz were not challenging ,it was just too easy to pass, and this actually takes away the very reason they were employed in this course.

The course is not very detailed and misses to explain key concepts. Terminology is used extensively without much explanation.

poco contenido práctico

The content is good, but the final assignment is ridiculous. The instructions are horrible, the peer reviewers are a joke (there are many people there with 0 experience with databases giving wrong feedback), and you don't get the answers for reviewing other people's works.

The course in itself is quite good, although there are many concepts presented in a few videos only.
The bug flaw is the final peer review assignment. Questions are unclear; It is a pain to complete. When reviewing your peers, expect the same issues: you are left alone to interpret if what was done corresponds to what is expected. I guess instructors intended to make something simple but it is definitely not.
And the most frustrating thing is that this has been a recurring complain (see the forum), and nothing has changed so far.

The course was okay, but the last Peer-graded Assignment was totally unclear. A lot of other students reported this problem on the discussion forum, but nobody handled this. Some students tried to ask questions, but any menthor answered back in merit. Of course if nobody understand the task then how can we rate each other? It is not fair. I think some examples can help on this problem.

This course offers very useful high level overview of concepts and ideas which make you feel confident in the long run. However, the course is extremely basic and does not go deep beyond the high level concepts. The hands on exercises are boring and do not engage students. The course needs to be improved to make it more useful for students. This course is not very worthy of the money.
