This course is designed with beginners in mind, and it is an excellent introduction to SQL. I intend to further my knowledge of SQL after taking this course. The instructor did a terrific job.

Great introductory to the SQL programming. This will definitely not only add another programming skill but also give me more capabilities programming in SAS. I would recommend this to anyone.

Quizzes poorly and ambiguously worded, database carelessly extracted

Clear instruction, but quite easy. Would prefer if it was more challenging.

A reasonably good course but not of the calibre that I've come to expect from Coursera. Assignments were poorly worded and clearly not thought out properly. The mentors also appeared inadequately prepared and were largely unhelpful. I think with a little effort the course could be tidied up and meet the standards I have experienced in the other Coursera courses I have done.

Was in need of a class to get back into database and this class was just perfect. I wouldn't say it's for a complete beginner or at least not for me. I was glad I had one to two database classes under my belt. Otherwise I would have difficulty following the class. The final assignment was tricky in it's wordings. But it's doable as long as you have watched and followed all the video. Sadie, the instructor is a great speaker and is very clear when she speaks. The best takeaway from this class was the very last video from Week 4, where she talks about lot of good practices one should follow when programming. I will keep it in my mind, definitely.

This course has great potential, but as of February 2018, it is still not fully fledged out: the lectures focus on general SQL examples with data science mostly in the background. The part that I found the most relevant with regards to data science was the final peer-reviewed project. Sadly, the studied data set was badly truncated to an arbitrary size of 10,000 records in each table, without taking into account relationships between records, which made most attempts at any kind of analysis dubious.

El curso fue muy básico.
En mi opinión hubiera sido mejor si los contenidos de las semanas 3 y 4 fueran más prácticos.
Las preguntas del examen final tenían una redacción muy pobre y ambigua, y no había mentores encargados de solucionar dudas.

The lectures are fantastic but the final course project was a nightmare that was poorly worded so that you had to spend a long time trying to figure out what the questions meant before you could attempt to answer them. Also the database was restricted to 10,000 rows which meant that when trying to answer questions there were so few relevant results from queries you couldn't do much. This resulted in even more wasted time. There was no mentor help on the forum that was actually useful - other people had asked questions based on the same issues and the responses were of no help.

Only reason I did not give this class 5 stars is because the final project is horribly organized and very difficult to through - it doesn't test your ability to use SQL or solve data science problems, but your ability to figure out what the instructor wants.
Besides that, the lectures are great and engaging (and short, so you can't get burned out), and SQL is very fun to use!

You can learn this stuff on your own. You don't need a course.

Just teaches SQL. Nothing is taught about how its used for data science

Really not sure how to rate this class. The lessons were great. I learned a lot. It was a good overview of SQL. The learning quizzes where you actually use SQL in the browser to answer the questions was slick. However, the final project was very poorly worded, most of the businesses in one table were not in the other tables because they did a poor job of selecting records from these tables to set things up which makes joins very hard to do, and the rubric at times didn't make sense or didn't even have you grade a question that you spent a lot of time on. I spent far more time on the project than I thought necessary.
So great course, terrible final project. 3 stars?

This is a good course for basic knowledge of SQL but the quizzes and assignments are very confusing and badly elaborated.

I think there are many things that could be improved about this course. It feels a bit rushed when it comes to the videos, which could offer a bit more information. There are some concepts that I had some difficulty grasping because they weren't explored with sufficient depth. And also, there are some other aspects which do not appear in the course, but which I feel would be useful, such as perhaps how to use database management systems themselves to extract data to your computer, since in this course you only learn how to write queries, and not how to extract the information you've queried to your computer.
In addition, I think the database used for the final task is flawed, and this gives some strange results when performing it.
On a more positive note, I did actually learn a lot from te course, and I think the proramming tasks where really helpful, and actually kind of interesting, as you get the chance to play around with your queries and experiment with the results (despite the aforementioned flaw).

I give it three stars because I did learn a few things.
I think my only recommendation is to add some more practise coding before the quiz available . For example, after we finish a video, have a practise code since coding is learnt by doing more often than anything.

I carried some advanced skills from Excel that helped me understand the subject better. I like non-scripted more natural story-telling like courses better. Otherwise I prefer more advanced tricks for programming. Overall, it was a simple to understand and start programming kind of course. Oriented for beginners, no prerequisites

This course is okay but I feel like they need more practice queries not just a test and you never got to try it before also the questions need to be better explained. Other than that I feel like I did learn the basics of SQL

Quizzes and assignments require a lot of knowledge not actually covered in the course forcing you to search for information elsewhere.
Questions are not clear in many tests creating incorrect answers which are not of the learners fault.

I Think this course makes a good introduction to SQL for analytics.
However I noticed many instances where the explanations were wrong or too simple. Many times I would get frustrated because having only a partial understanding of how the functiosn work leads to many mistake : " a little knowledge can do a lot of harm ". The wording was one of my worst fears when looking at questions, often it would not be precise enough and you would wonder what they really want as an answer.
But as I said it was for me a good introduction, I wouldn't call it more than an introduction. I also learned to learn SQL by myself and to find queries that could be done in a way that agrees with my own sense of logic.
Conclusion: good introduction, the course still needs some refining.

Good for learning basics of SQL but not much application and integration of concepts. In general, however, it is good for beginners.

Great Course to start with.
Gives a good understanding of SQL on one side en working with databases on the other.
A syllabus of al the code examples in the video's should behelpfull

Certain quiz questions were unclear. Final peer-review assignment had unclear/ambiguous questions that didn't fit with the data in my opinion. But content is useful. Delivery could be improved.

Good program for beginners. Peer review assignment needs to be updated. The assignment is not graded by instructor. Certification means nothing because anyone who pays money will eventually get it.
