评论日期：Jul 1, 2021This course gives a precise idea about only checking the timing performance. this will help when there is a big chunk of queries where there are multi level execution is required. otherwise for single chunk limited result codes these terms are not needed as per my opinion. The instructor should try to explain a more about the function of the things or provide some links for the students to study.As a guided project the content was absolutely fine and to the point.
