"one star for the certificate;one for let me learn basic knowledge of SQL;the website often breaks down,so is the Teredata system ;the problem-solution system is also troublesome,hard to get the solution on time, maybe it is better to set a all-time online problem solver. No answer for teredata exercise also trap me for the hint in the teredata excersise sometimes not clear. Hope advancement for this course and the better experience of users."
