The lecture content is too short compared to the tuition fee. It's not that the lecture content is bad, it's good, but it's too short, so I can't give it many stars. 
It's worth watching once, but since it's expensive compared to free lectures on YouTube, 
I wish it was a little more substantial and filled with more content.

[A hundred words are not as good as seeing once] Advanced SQL for data analysis

Hello MOA AOM, 
First of all, I apologize for not being able to provide you with a satisfactory lecture. 
This SQL lecture series by Datalian is designed to help students learn SQL concepts and solve problems themselves. Among the numerous functions of SQL, I tried to convey only the most essential core functions used in actual work, so I think it did not reach the amount you expected. 
I will come back with more substantial content in future lectures :)
