DATABASES AND SQL FOR DATA SCIENCE WITH PYTHON からの人気レビュー
I found this course really exiting as I learned how one can manipulate large data from within sql API. I also appreciate platform that provides means to practice python as well as sql code.
Overall is a nice course. It was a bit confused because Handson Lab related to each other. It would be nicer to have a short remind from previous labs or better to keep labs independently.
One of the best course I completed on Coursera. All the learning material is well organised and easy to understand. Also the non-graded sections regarding relational databases are interesting.
Best course with best difficulty and best skills as per the title . i love this course becuase it has esssential skills needed in terms of developing the right skills for data science .
