The videos were pretty high level, but provided at least a foundational knowledge of a variety of topics. I think the videos could be more in-depth. The final assignment needs some help. It has some great practice opportunities; but someone needs to provide detail about what the tables contain. It took a long time and some searching on the web to find the definition of what is in the tables in order to successfully complete the assignment. All Coursera would have to do is either provide a link to that information or provide a summary themselves in order to make the assignment better.

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.

While I liked the content, the paste of teaching was fluctuating. Sometimes the instructor focused on definitions for multiple minutes which was good but then sometimes she just mentioned lots of technical stuff without a walkthrough syntax. Apart from that, there were some syntax mistakes on the video like closing a parenthesis without openning one. Last but not least, editor of the video could have done a better job, removing duplicated dialogs and better timing on cutting and assembling the video. With all that being said, I learned a lot about SQL using this course.

The interface, video demonstrations, and lectures are good; however, there is a lot of information; its hard to go back and review the information unless you re-watch the videos; there are no handouts or other notes you can reference. The quizzes and assignments are difficult to complete due to some errors with the quiz content. There needs to be glossary of terms that the learner can reference during the quiz. I'm only in week 3, so maybe the remaining weeks will get easier now that I've practice with SQL syntax a little bit.

The course covers a lot of worthwhile, useful material. But some of the lectures are poorly written. Be prepared for what the instructor says to not always make sense, or in some cases to be wrong.

The final assignment is more involved than the course materials indicate. Also, one of the questions in the final assignment is ambiguous and needs rewording. Of the five answer sets I saw, mine and the four I graded, two made a reasonable but wrong interpretation of the question.

This was a useful review of the material for me.

The course content overall is very good, with assignments being appropriately challenging and thus facilitating learning better than some other introductory Coursera courses. That said, the final assignment in Week 4 is an overkill, and the estimated duration needed of 2 hours is a severe underestimation, especially taking into account the fact that it is also peer-reviewed, requiring not 1 but 3 reviews. If you are taking this course with a deadline in mind, do leave plenty of time for the peer-reviews to come in.

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.

Would have been nice with more use-cases for some of the aspect of writing queries. For instance, use-cases and examples for using different types of join, using case with text, numbers, dates, etc., more examples of subqueries, and so on.

The written assignment is worded pretty porly in some sections making it difficult to understand the aim of the question. Further, doesn't seem like instructor clarifies these issues with many posts in the discussion forum being left unanswered for years.

Mostly good content to get started with SQL but it very heavily leans towards theory, some weeks have no examples in the video lessons, or the code shown is not even run to show the results. The learning objectives in the videos last almost as much as the actual content of the course. Practical quizzes are not entirely related to the lessons and often cover subjects that weren't instructed. No feedback is given on these quizzes so they are not helpful if you didn't get it right.

There were times that I felt like I didn't understand the material enough and the examples were sometimes lacking. Also the final assignment was really poorly worded so it could be difficult at times to understand what the questions were asking for. but overall. it was helpful. If you don't know a thing about coding I would advise that you look somewhere else, since this class expects you to know the basics about coding. However if you are familiar with coding it is passable

The content of the course was good. Sometimes I got lost during the explanations, because the professor did not point to the board to help us follow what she is talking about.

The assignments also were interesting and helped us understand the theory. However, sometimes the exercises were not clearly written. I also found that there is little support in the Forums, giving the impression this is an abandoned course, which is a disrespect for those who paid for the course.

I think this was a good course but it is not enough on it's own. I suggest doing your own reasearch and seperate studies on SQL to get a good grasp on the topic. I would much rather the videos not focus so much on the speaker but instead showed more visuals and better examples. Also the videos do drag on and repeate the same points couple of times. This is a good starting point for a begginer but I do not reccommend for anybody else who has more experience with SQL.

The initial classes were really good. But from Week 3 onwards, it was getting a little complex. And in the course while showing the examples, the lecture does not show the output because of which everything was bouncing off my head. Similar thing happened in Week 4 classes for a few cases. For a beginner who has not experience SQL at all these issues will badly effect their progress and will leave them clueless making them to think for a different choice of course.

The exercises were extremely helpful to practise the concepts but I struggle to follow the video tutorials. While it was useful to have the coding / working displayed on the screen, I wanted to also see the output so I know what it will look like. The Peer Review assessment was also hard to work on as some of the questions were not worded clearly. Otherwise, I do think this course met expectations and I have a much better understanding of what SQL can do now!

This course could be formatted better. I think that watching 45 minutes of sql content with no opportunity to practice until the end is not condusive to knowledge retention. A learn by doing approach could be implemented so that learners practice queries as they watch the video and learn new syntax. The content in this course will be applicable to the real world and lays a good foundation for more learning in the data analysis space.

This is an introductory course for SQL. While the course does cover basic topics at times this feels very shallow and fast. There is a massive gap between the quality of the tutorials and the difficulty of the graded quizzes. I had to resort to hours of study outside of coursera using different resources to help me complete assignments. I would not recommend this course. There are far more thorough and free courses on youtube.

The videos were nice and easy to follow, and the quizzes were good too. The first part of the final assignment was fine, but the second part was very confusing and difficult to understand, so completing the course became quite difficult. Also, it seems like there was very little help to get through the forum for the final assignment, which just made it more difficult. Would give 3.5 stars, but I can't give half stars.

The instructor was good but could have simplified the queries and then have taught it to us.

I joined a SQL course on another portal to brush up some concepts and then came back to this course as the instructor and the pdfs weren't exactly clear. Overall, the courses were good and a little pre knowledge is required for this course. A person who doesn't know anything about SQL can't have an easy path with this course.

This is a mostly a course intended to review, that's to say, you need to have prior knowledge of SQL if you want to make the most out of it. If you're just a beginner, I wouldn't recommend it though, there are a lot of things that remain unspoken and are important. Readings are okay, but in my humble opinion they fall short to what SQL world can really offer. This, I consider it mainly a sneak-peak.

It is a good course but could be better. beginners find it hard to understand what Mrs. Sadie actually means as some lectures are missing examples to better understand. I found the prompt reading by the teacher a bit flustered too which made it difficult for me to grasp what she wants to convey. I don't mean to be rude that was my personal experience. the first 2 weeks are fine though. Thank You.

It's a nice start for beginers, the videos and the quiz between courses are good.

But, maybe you should be more responsable with the final exam, it was not so clear considering english it's not the natural language of us and not always its the same to translate and to interpretate. By the way, the database used in the last exam requieres a check, and please, enable "INSTR" function in SQL fields.

I think there were some explanations which were confusing but I did learn a lot. I wish the course utilized the sandbox for questions. While starting out using the encoded SQL text boxes on the quizes was very easy, going into the sandbox I think would replicate a more typical environment. I understand simple structure of SQL, but I have no idea how to use it outside of this course.

Good overview, and you will learn soemthing for sure. Some course notes would greatly help. Also, sometimes in the videos it could help if a cursor would highlight on which part of the slides we are currently talking about and the SQL code in theslides should always go woth the output, so that a beginner can easily grasp what is going on. Some mindor mistakes in the assignments also.

It did a good job of explaining stuff, but it is just hard to connect the actual coding with the concepts since it did not provide following up coding practice to allow the student to practice them. Instead, this course introduced a whole bunch of new concepts and you only got to practice the coding at the end of the course, it is just confusing and frustrating to follow through.

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!
