Great intro class for writing queries, lots of good practice and I like how much more challenging the material gets as the weeks and exercises progress.

Muy bueno, me ayudo muchisimo a comprender este campo con respecto a MySQL. Buena forma de enseñar por parte de los instructores y la ayuda pertinente.

I loved it. It was a lot of work for me. I knew nothing about SQL and i was hard at times but It is so great to know and I loved working in Teradata.

The course is well designed. There are real business data for you to explore by using MySQL and Teradata. Have a lot of practice. Highly recommended.

10/10 nothing to say, actually is the first online course that works even counting my university's classes (pls put the dognition relational schema)

very useful and easy to understand. Hope it will add more information about how to build a database which i think will be very useful to actual work.
