I learned a lot in this training and I find it very enjoyable and interactive. There a lot of concepts I thought was complicated but was explained well by the trainer.

I quite enjoy taking this course. Matt is a very good instructor. He can make complicated things easier to understand.
(4.00 out of 5) Joanna [ 17 September, 2020 ]
The instructor was good at providing real world example whereas the course examples weren't always very relatable
(5.00 out of 5) Wendy [ 17 September, 2020 ]
as far as my role goes, the second day was significantly more useful than the first day. The first day was about creating databases, functions, views, procedures, none of which I can use in my work system. I thought the group set, over() and subquery lessons to be particularly useful. I would highly recommend the second day to my coworkers
