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.

The course was pretty good for a beginner. The instructor was very clear and explained all the concepts in a very easy to grasp manner. However, the entire course could do with more coding exercises. Concepts such as joins, group, etc could be better understood if there were more exercises. Also, during the coding exercise (at the end of the week) it would be really helpful if correct answer and an explanation would have been provided. Having said that, its really good for beginners and I would and have recommended this to others.

=) Very clear walkthrough of important concepts in SQL and why use certain functions for certain tasks.
=( Wish there were more practice questions so it's more interative.
=( Also it would be great if there are more "real-life" SQL practices that involve solving for an actual question that you might encounter as a data scientist working for a tech company.
Thanks so much for sharing this with us, Sadie!

Thought some of the intuitive thinking was a bit challenging, but really liked how the sqlite server was built into the course and didn't require any download or off-site work. Think some of the time estimates should be a bit longer, but overall good course.

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.

A nice course for introduction with SQL but they could have used the software currently used in the industry like oracle's MySQL or SQL server.

Would have been better if there was a chapter on connecting to an sql server from an application or gui.

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.

This is really a good basic knowledge course. Actually the more usable commands will be convered

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.

Although the information and topics in itself are interesting and the course gives a good overview, the individual videos have a lot of repetition (in 5 minutes an intro, the main part and a summary), and I find the person who gives the course hard to listen to, as it often seems like she doesn't understand what she is saying. Also the questioning in the case study is very unclear - watching the discussion forum I'm not the only one who struggled to understand what they want. The provided answers for reviewing your peers are so widely interpretable that I myself got max points from 2 students for 1 question, while the third gave 0 points. And that for several of the questions. Overall not satisfied over the quality of this course

Lectures were stilted and repetitive, some of the exercises were poorly thought through and the peer-grading is a joke, with people grading me as having got questions correct, when having seen the answers I now know I got some questions wrong! Questions from peers went unanswered in the forums.

It stars strong, but on weeks 3-4 it lacks comprehensive examples and guidelines, and that makes you feel lost. Also, the final assignment is very hard, and it asks things in a non-comprehensive manner, which makes you spend a lot of time until you understand what they are asking you.

Considering how hands on learning a language like SQL can be, this course does a lot of info dumping about the theory all at once instead of embracing the practical approach. This makes the course a lot more taxing than it has to be.

The teacher has really good knowledge of SQL and I really respect her for that, but as someone who is not familiar with SQL finds it difficult to give quiz without any side by side practice of the topic
