Лучшие отзывы о курсе DATABASES AND SQL FOR DATA SCIENCE WITH PYTHON
Course is god enough. However the last assessment is not. Misprints and not clear questions lead to disappointing marks in the end. Also other students marked assessments based on their understanding.
Most of it really good. I think joins should be covered in the base material and there should be less of an emphasis on sub-queries. The Peer Reviewed final was a little confusing in its questioning.
Databases and SQL for Data Science" course was good. I learned too many new things and it really helped me by providing fundamental knowledge regarding databases and SQL.
Great introduction to basic manipulation of SQL tables and working with the IBM DB2 databases by connecting to them with iPython. Very straightforward explanations and very enjoyable tasks.
