It is a very introductory course on SQL. I have never learn any SQL before and I can catch everything she said. People might find it extremely easy, but in learning programming you must make sure all the basics are well known to you before using them in more complex situations.

Excellent course in all basics of SQL.

Built-in sandbox is the most important plus of the course.

A lot of practice, a balanced number of lectures.

At the end of a good project that allows you to try out all the methods learned in the course.

Excellent.

I loved this class. It was the perfect introduction to SQL coding. It was easy to follow and I learned a ton. -Rick

Comparing to other stuffs, this is really brilliant

Good course for anyone starting to learn SQL but the course needs more assignments to ensure that the learners have got a good understanding of the concepts. Also, the final project is a bit overwhelming to do without prior experience in SQL.

Examples, examples, examples. This course could be drastically improved by providing more concrete examples of each function, preferably one we can play and explore with in some exercise (not just a practice quiz) if not right there in the lesson (much like w3schools does). I felt that this would have increased my understanding, confidence, and proficiency exponentially.

Considered as a beginner-level course, the lack of depth may make some sense. However, the assignment is poorly organized and worded. Even worse are the reading materials that include lots of external sources of casual articles. Some of the contents really should be digested in the course chapters.

As a beginner I found the course useful, but I also had to look for stuff on my own and I was lucky enough to be able to ask an expert when I got stuck. Also, there's some good stuff by other learners in the course forum. The explanations are often not very clear, and there no tables provided to be able to follow the code. In addition, there were several typos in the code, which can be very confusing when you're starting because you think you're missing something. In one case in particular (explaining self joins), Sadie copies her example from another website which she doesn't identify (https://www.w3schools.com/sql/sql_join_self.asp) and she copies the code wrong. The database for the final assignment was really confusing and badly structured (again, confirmed by my 'expert', who used some code to show me why), so doing that assignment was unnecessarily painful. The only really why the course high such high average ratings may be that Sally is really sweet but I wish I had known all this before I took this course.

lessons are not well structured, it would be so much more easy to explain sql

interactively by explainging a concept of sql, then creating a query highlighting what is particularly important of that query and then seeing the result of that querry. Instead it is done in old fashioned power point. First a set of concepts, then some additional information and then application,

E-learning allows for a much more interwoven structure, that might be more initial work for the creator of the course but it clearly would add a lot of value to the students.

Sometimes the course misses to explaing relevant detail.

For example in the last weeks lecture about Date, we learned that we could do operations like

Date('now') - DateColum, and this would return the time difference but only in years, not days, not hours. It would be intersting to know why that is.

The last assignment

Bad teaching. Static slides so you don't know what part of the slide the teacher is talking of. The teacher stumbles upon words every few seconds which makes it hard to follow. Why don't you just cut these out? You're getting bombed with information with no practice. The practice will follow after the bombing so you can't remember what the teacher was talking about at the beginning. Why don't you follow the rhythm like "teach something - exercise it - teach something - exercise it". Now it's "teach, teach, teach, teach, teach, teach, teach, teach, excercise"

The task at the end is ridiculously much work. Should be splitted all over the course. Also nobody wants to review that much stuff.

What's good? Well you'll learn the SQL basics but it's a hard fight until then.

These lectures seem incomplete. For several sections, I had to Google more information to understand the lecture topic.

This course is listed as a beginner level course with no prerequisite, but throughout the lessons I felt like I was missing some key basic information. The course recommendation is 20 hours, 3-5 hours a week. The first week fell into that parameter, but after that the hours required increased each week, with the last week being about twelve hours including the final project.

Ideally, this course considers adding in more complete explanations for the examples in the lectures (including outputs), more practice coding, and more depth on exploring data and making inferences from your queries.

Some of the quizzes do not make sense and I have to select something that is wrong to pass. It is really hard to follow sometimes and the content of the video mostly does not relate to the content of the tests. I had to google most stuff that came up in the videos, many quotes from w3 school (another provider of programming courses).

I choose to pay for courses on coursera so that I do not have to read through tons of free material online or get quoted content that is for free on other learning platforms. This course taught me some neat things but mostly wasted my time.

not the best course for someon who is a total beginner( that is has 0 experience in SQL) better for someone who already has an undertsanding of the language and is simply just looking to get certified. as a beginner I have to do an entire course through youtube to understand and follow along with the course, because here I was bombarded with technical terms and there was no practice example which I could follow along to gain relevant understanding. personally I used a course on youtube by freecodecamp to understand the concepts and to be able to try the concepts.

I finished the first course in the series, however it quickly became apparent in the second course that the instructors are unprepared and the assignments are thrown together without student learning as a priority.

If you want to learn SQL or Database systems, I highly suggest taking "Modern Big Data Analysis with SQL" from the CLOUDERA team and "Data Warehousing for Business Intelligence" from the U Colorado team.

Both of those course paths are much more informative, structured, and up to date. You are wasting your time if you choose this path.

This was a shockingly different approach to teaching a software language. I did not enjoy the style whatsoever, and found myself constantly seeking outside sources to understand what was glossed through. Unless you have a strong programming background, I would not recommend this particular class. Instead, seek something where you will complete SQL code yourself, with explanations of syntax, structure, and purpose, specific to the format you will be using. You'll do yourself a favor by doing so.

I felt the course was put together in a hurry. There was a lot of information that was incomplete or just plain incorrect. The assignments were even more vague than I was expecting. OTOH It does lead you through learning very basic SQL.

Too much focus was given to SQLite which is not an industry standard. Perhaps using a free DBMS like Postgres or MySQL would have been better. Are there any interactive T-SQL or Oracle engines that could be put in a box like the SQLite here?

This is the first course from Coursera that I didn't like at all. For absolute beginners is not suitable. There is only theories and somehow boring because there isn't any examples to do at the same time to understand the content better.

I recommend to add more examples to the weekly courses like the ones for the final project so we can understand the theory more.

This course gives a pretty good theoretical overview, but is not practical. There are limited exercises and often the examples are poorly explained. Someone starting from ZERO SQL experience will not succeed in this course. You would be better off going through https://sqlzoo.net/wiki/SQL_Tutorial and then returning to this course.

Nice course! Only giving it low stars because the assignments are so out of data. Please update your assignments corresponding to updates to Database.

Hola, no es tan bueno que no puedas correr código mientras aprendes con ejemplos.

It's very basic SQL, definitely not challenging for anyone with SQL experience

During the course, I wrote a review, and gave three stars. But now, I sense the need to change it and add to it. Yes, I have actually changed the final rating from three stars to only one star. (Below is a quick review, because I don't want to waste too much time on it.)

In the beginning, it was claimed that certain participation in some so-called "discussion" was optional, but you had to participate in order to even be allowed to move on with the course. So the claim was false, and no one cared to take care of it. Or if the claim was indeed true, then indeed you did not have to participate, and it was indeed optional, and of course in that case you would not be allowed to move on. Either way, this immediately created a "bad taste" so to speak.

There seemed to be errors or sloppiness in the quiz questions and in some of the sets of multiple choice answers, which was annoying. Some quiz questions were not very clearly put, so sometimes -- I would even say often -- it was difficult to understand the question. Sometimes it also seemed as though some of the quiz code questions suddenly went too far compared to the material taught, which is in part due to the course's lack of practice.

The instruction videos were also poor, because they were not very well optimized. For example, the instructor's audio had a lot of "wet sounds" in it, so to speak. Also, the instructor's teaching was unpleasant to listen to, because it sounded awkward, as though overly scripted or very unnatural. There were also errors where some word or name did not match with code on-screen. Maybe she is a good instructor outside of Coursera, but you could not tell by these videos. Sometimes, the audio was even cut off, or so it seemed.

Because of the earlier mentioned lack of practice from the course, you must do a lot of practice yourself. I already knew some things here and there, and usually find my way around computers, and so on, anyway, so sometimes I had an easier time. I also understood some of the statistical concepts they asked about later on.

But even if so, I decided to quit during the final assignment, because

(1) in the beginning of the final assignment (or rather right before it) it was unclear how to proceed on Coursera itself about it, and I wasted time finding out;

(2) because of the course's sloppiness, it looked as though, after using only SQLite in the course, you suddenly had to use MySQL in Coursera's online sandbox (which may not have been a big deal, but is still strange a choice for a course), but really you had to enter some link and use the online SQLite interface with the Yelp dataset, which I only found out after roaming the so-called "discussion" fora for some time, wasting time in doing so;

(3) the assignment itself had questions that should not even be asked, because some of the (statistical) topics were not even covered in the course, and, again, there had hardly been any practice in the course itself to prepare you, making it an even poorer course.

I read some of the other reviews, especially the ones criticizing the course. Overall, relatively there are not that many giving low ratings, but they are right: it really is a poor course. I don't understand why the course has such a high score.

In short, it is a poor course, no one cares to update it properly, and I would recommend to any other course taker to get the most out of it, preferably for free, and then to leave as quickly as possible.

The best thing I can say is that the deadlines motivated me to complete my week's studies. Unfortunately the instructor, content and presentation were really poor for this course. The quality here really serves as a stain (in my eyes) on the reputation of UC Davis and Coursera.

The instructor continually stumbled over her words as she read whatever teleprompter she was reading from during the presentations. It appears she didnt write the presentation herself as she stumbled through her presentations often creating wordy non-sensical explanations. It appears she never practiced the monologue before filming.

In addition there were many mistakes in the code in the powerpoint presentations. This course has been around for many years with hundreds of thousands of students. You'd think that by now they may have decided they should re-film the course and correct the simple and blatant errors that any complete beginner can see clearly in the presentations.

Otherwise, it's an ok course if you want to use it as a starting point to your self-teaching. I would recommend anyone taking this course to study with other materials on the side as well in order to truly become proficient and to help them know the subject matter better than the instructor who clearly is no expert due to the many and simple mistakes she propagates through her course.

This was the first course I ever took on Coursera and I honestly wondered if they were all like this and how Coursera was able to stay in business. I stopped halfway through for a variety of reasons. The instructor was incredibly awkward on camera and just read a teleprompter the entire time. I ended up doing some other courses (by other instructors) and realized how many basic pieces of information she had left out. There was very little hands-on practice throughout the course and the quizzes wouldn't even show you the correct coding if you got it wrong, so you weren't able to learn what you did wrong. Glad that I have found some other courses to take on this subject, but I'll be avoiding this teacher/school from now on.

This is not a beginner course, it is very high level with little time or explanations spent on each topic. The quizes expect syntax that has not been gone over in order to correctly answer the questions. I received better explantions for what was needed from W3school brief high level explanaton then I did this ocurse.

The instructor tends to stumble over her words alot which causes confusion and the examples within the presentation are not really clear as they arent based off real world, just table 1 table 2 etc.

I debated if I should review or not as I wonder also is this just not witin my leanring style, but reallized in a course of this type it should fit a variety learning styles as the Google courses do.
