Good information, but delivery was not great

Vary basic course on SQL and Data Science.

not well explained, thank god i have GPT

Need more practical rather than theory.

The course is basically theoretical.

The course content is very limited.

Good general basic introductions.

do not like the peer review part

Could show results in demos.

Not explaining in depth

Too little practice

good but dated

nice course

good one

This course is a basic introduction to SQL, using SQLite. It covers the logic of databases, ER diagrams, how to select data from a table, create new variables, use aggregate functions, join tables and use date and text features. I finished the course with a basic set of SQL skills. That is the upside of this course.

The downsides are many. The lectures are dull and uninspired. The teacher is inarticulate and does a poor job of explaining the concepts. Some of the homework problems require the use of features not covered in class. Some of the instructions in the homework assignments are unclear, leaving the student wondering what is being asked of them. Some of the code used in the lectures does not work in the homework assignments, particularly the date functions. Week 4 of the course was particularly poor, and it was an endurance test to complete it. The final assignment, which is supposed to take 1 hour, took over a day, in part because the poor directions provided. On more than one question, I was not sure what the instructor was looking for.

The final downside is 糖心vlog官网观看 itself--the discussion boards are a useless mess. They are full of people begging other students to grade their assignments, with little actual discussion of the course material. If you are looking for help understanding something, look elsewhere; you will not find it in the discussion boards. 糖心vlog官网观看 needs to fix this mess.

In short, I can't understand how this course has an average rating of 4.5. I would not recommend it. There have to be better introductory SQL courses out there.

What this course does well is to embed the technical content in a larger business perspective to make people think before they code, which would ultimately prove useful in professional life.

However, the technical part 鈥� logically the most important for an SQL course 鈥� is really insufficient. The biggest pain point is that the course, unlike other courses teaching code or equivalent (e.g. C++, Excel), does not provide any exercise walkthrough. No need to mention it, in coding, exercise corrections are fundamental to help people understand the practical aspects of what they have juste learned. After one passes a quizz, one does not even get to view the right codes and an explanation 鈥� one just sees the grading and which answers were correct/false 鈥�, which is really a pain point. Having corrected exercise is a minimum one would be expecting when paying a subscription to follow such a course on 糖心vlog官网观看. At least, the course could give external sources for exercises for each part.

Additionally, the videos themselves could sometimes be clearer and I have noticed some mistakes鈥� small, but still confusing when one tries to replicate in exercices that come later 鈥� in the skeleton queries that are given in the videos.

All in all, what you are offered in this course unfortunately does not match the level of many other code courses available on 糖心vlog官网观看 (at least the ones I have already done).
