I thought this course was great! Great introduction to Relational Databases and SQLite. Highly reccomend for anyone new to SQL, Databases, or someone looking to get started with a data science career.

This course has really helped with optimizing queries that I work with everyday, enhancing my understanding of RDBMS, joins, analyzing and structuring exactly what you need and yielding those results.

I think the course is interesting if you don't know anything about SQL, if you already works with it, you can learn something about formatting or maybe some functions but I think it is for very beginners with SQL language. In any case, if you don't know anything about SQL is a good course to learn the basics about it and start with an introduction of data science.

The course is pretty good. In particular, the quizzes and assignments are very useful to understand the concepts that are being taught in the course. I enjoyed it!
However, I will give only 4 stars because regarding the lecture videos I would have preferred that the instructor coded along with a sample database instead of showing the code snippets in a power point.

I thought this course was really useful for beginners in SQL, my only issue is that some of the concepts were not explained very well. I never really understood how to qualify tables, there were things you could do with text that were mentioned but never explained, etc. Maybe I missed something but some of the concepts they were very vague but then on the quizzes

The modules are carefully planned and precise. The reading materials are really helpful to get a better understanding of the subjects, and the quizzes at the end of each week are thorough and cover every important point. The one thing I can think of that can be improved is the way the teacher is presenting the lessons, it is unfortunately a little bit monotonous.

Thanks to this course I've found a job as data analyst, and now I write sql queries every day, which eventually make me sick of the select......from.....inner join*n......group by......lol Anyway it's a very efficient course that gives you all the necessary building blocks in a week (I finished it within several days). And the rest is gained gradually from work.

Overall great course! The lectures and lessons were extremely useful! However, for the final "project", it would help to have write access or some option to create a temporary table with either a WITH or CREATE TABLE VIEW clause. Also, maybe some documentation on what SQLlite methods you and can't use (e.g. you can't seem to use INSTR when cleaning text data)

This is a great opportunity for a beginner to learn the basics of SQL for data analysis. I'm confident that I can put SQL on my resume now! The end of the course is pretty worrisome though. It takes a few days after you've submitted your final for other people to finall review yours. You'll end up doing wayyy more reviews just to get others to review yours.

The instructor is great, explains everything nicely. The peer-reviewed assignment at the end was a real shock though. Hard to understand the instructions and quite a lot of work to do compared with the other assignments. I spent a lot of time on it. Then it is marked by one of your peers so you have to hope that you get someone who markes you fairly.

It is a good course for beginners who are not familiar with SQL. You don't need to install anything but can still practice through the quiz to enhance the basic commands.
The problem is there are some mistakes in the course material and these wrong explanations may be misleading for the students who are new and don't have sufficient knowledge of SQL.

I did enjoy it quite a bit. Unfortunately the peer review process can also be kind of a curse - none the least the clear possibility of fraud (I detected two assignments with the exact same final answer - not a couple of lines, either. Quite the long, detailed answer). But it was fun and the teacher was pretty good and expressed herself well.

I thought the course was, by and large, effective at communicating the lessons. The weekly quizzes and practice elements were also great. My only sticking point was in the final assignment. Having to update a .txt file (which is notoriously difficult to format) and review others' .txt files makes for a bumpy experience for the final assignment

Content is fine but I feel that the last peer review assignment could be improved by adding much elaborate data definitions and metadata to give better clarity about concept of fields. Just UML diagram doesn't suffice for in depth analysis. Also, please allow a better sql editor to use, just one query at a time is bothersome.
P.S: Good job!

I'm totally new to SQL and even as a beginner I found these lessons to be way too slow, assignments were interesting but the questions of the peer review were very difficult to understand. The teacher is very clear, the structure is logical and she's able to give good simple tips. I'll recommend this course for whoever wants to get into SQL

The course structure is quite upto the mark and the lecturer Miss Sadie explains all the concept in an interesting way. There are 2 scope of improvements I suggest for this course:
-Using MySQL instead of SQLite because SQLite isn't used much in the industry
-Including Windows Function in this course itself instead of the other course ahead.

I had issues with week 3. I think the outputs should have been included with the code during the videos so the examples would be more helpful. The forums were very disorganized. I commented on a post and asked a question but didn't receive help on either. Overall, I was happy with the class and am looking forward to the next one.

This course gives a really good introduction to SQL, no pre-knowledge needed and it feels like the level reached at completion of the course is very satisfying for a 4-weeks program.
The final assignment is a bit confusing and could be improved, but the lecture videos and practice quiz at the end of each module are very well done.

Liked the lessons a lot, the examns and the assignment is slightly more complicated to the queries shown on the videos though. The level of exercises shown in the video lessons should be higher so students know what to expect from the exams and assignment. Aside from that, explanations are clear and the course is very enjoyable.

Great material and videos. However, the questions on the final are ambiguous and can be very challenging, and the final as a whole can take much longer than the anticipated 2 hours. On the other hand, if you can make it through the final, you will come out with a great introductory understanding of SQL by the end of the course.

I enjoyed the course and definitely know and understand SQL statements now. In the future, it would be helpful to provide additional tips on where to practice your SQL statements to help those of us who need that extra help.
The instructor was very clear in the videos which made it easy to follow. Thanks for a great course!

Aside from stumbling over words, and clear video cuts, I think the course was effective, however there could be improvements but showing more examples during video demonstrations and more detailed explanations. Some parts of the course tells you to do something without properly explaining or demonstrating the WHY behind it.

Great course but could be better! I think the teacher should be more informational, and instructional in how to complete said tasks. I am currently taking the data wrangling course and that teacher walks through problems, and I think this course could benefit from doing the same. All in all a great course, but room to grow!

The course was informative and well- structured. However, I wish the course had more example problems in the lecture videos. I also wish the lecture sides showed the results of each query instead of just listing out the query. Overall, I feel like I had a good overview of SQL and some rudimentary knowledge on utilizing SQL.

I learned a lot but I needed a lot of extra tutoring from my husband to really grasp some of this stuff. There needs to be more examples shown of data, SQL and output, not just SQL. And there needs to be more practice of basic queries to really get the foundation down. I feel like I was scraping the surface of the basics.

Great course but will require focus, and dedication. Course teaches to its best ability but leaves out a few concepts that could be driven deeper like LIMIT, distribution, and few others. Overall great course but little difficult! Use outside resources to your advantage during this course to help grasp the information.

The course is easy to follow, well-explained and have enough hands-on to reinforce what we have learnt! However, the assignment and quizzes can be improved. Sometimes the contents of the quizzes are not covered by previous videos. Over all it is a good class for both beginners and people who want to refresh SQL concepts!
