Hi there,
We are currently carrying out some research on the understanding and usability of different relational schemas (as part of a Ph.D. student's thesis work).
We would like to invite you to contribute to this research by answering a small number of questions on SQL query interpretation. Participation is via an anonymous form and there are only 7 questions, so it should not take more than 10 minutes of your time:
We thank you in advance and would appreciate it if you could also share this research with colleagues who also have a background on SQL.
thank you,
João Paulo A. Almeida
