and provide insights to make better decisions and optimize their businesses. This is a data scientist, “part mathematician, part computer
scientist, and part trend spotter” (SAS Institute, Inc.). According to Glassdoor, being a data scientist is the best job in America; with a median
base salary of $110,000 and thousands of job openings at a time. The skills necessary to be a good data scientist include being able to retrieve

A comprehensive course that covers major aspects of query building and retrieval in a management system. The topics were delivered well and the materials/assignments were relevant for skill-building.

Well it was a short course, the assignments are a little bit repetitive (mostly in the last). The course reviews every 'practical' aspects of SQL, how to assemble the bricks while writing queries,...

The instructor spent too much time on unnecessary and self-explaining topics, and on the other hand failed to explain some important details. I ended up skipping much of the course and googled a lot by myself.

Decent introduction. I recommend https://mode.com/sql-tutorial for a better introduction to SQL.

Assignments are very badly designed. Also the questions in the final assignment are unnecessarily repetitive!

The lectures were not easy to comprehend for a computer language. Though the course mentions it is a beginner-level course, the lecturer jumps to a certain part where there is a learning curve expected.

A little too easy, not challenging at all, given this is a beginner level class, I'll give it two stars. You could finish the whole course on Saturday if you get up early plus Sunday if you do not.

I'm not really that enthusiastic, too much talk and too little exercise

The teacher gave the impression that he did not have enough time (which is false because he could make many more videos).

Even reading the prompter throughout the course, the instructor has been extremely nervous and unsmooth in reading. This is the biggest downside of the course and eclipses its good sides.

Didn't feel it actually helped me learn because there wasn't any step-by-step instruction. It just was videos w/script and then quizzes and you were expected to know the content.

The instructor is so hard to follow that it made me not want to continue with the entire specialization. Although I really like the challenges and the idea of peer-reviewing.

Slides have many mistakes. I have experience in other languages but even for me, the lecture is far too ambiguous in some parts and way more details in some other parts.

Hi, First of all I don't like peer assignment concepts. second especially in joins videos if you have shown examples with output, little elaborate, will be more useful.

Below expectation for such a high profile university. Luckily my basic background in SQL was enough to get me through the activities because the lectures were poor.

I wish that the instructor used examples that mirrored the type of questions in the coding exams. We did not cover all the material in the coding exam.

The structure and guidance provided on the final assignment was very poor, resulting in far more time required to complete than expected.

Questions were often vauge and videos sometimes did not display the information being talked about. I found several examples confusing.

El tercer modulo deberia estar mejor explicado ya que muchas de las formas de utilizar las sintaxis y los codigos dejan bastantes dudas

too much theory, I needed something more 'pratical' that allowed me to start using and write code and not see a lot of slide with code

1.Very basic course.

2. Assignments level does not match with training level.

3. Need to provide class which includes query writing.

The teacher was not readily available to answer questions. The course was alright but I do not feel prepared to use my skills yet.

Very slow and badly organised start of the course with no to very little practice of how to use SQLite before the coding quiz.

Mistakes in videos, no possibility of asking quetions to the teachers. It uses SQL lite not used in professional enviroments

The first exercises are still ok. But the final exam is really a mess. The questions are not as precise as they should be.

Too much talking in videos with less examples. The exercises were vague and not enough information was given to solve them

Cannot do the final exam as I am not able to install the external software. Why can't the exam be done within this app.

The videos had the wrong emphasis, and were far too long.

More time should have been devoted to the exercises/quizzes.

Rather slow-paced and not maintained anymore. You learn only absolute minimum. There is no good practice hints etc.
