SQL Nulls Survey

University of Edinburgh, ENS-Paris, and data.world run a joint research project whose goal is to understand how SQL nulls are used in everyday practice. Towards that goal, we have created a survey to be filled by database researchers and practitioners.

We greatly appreciate your participation; your answers will help create new tools for handling incomplete data.

We are awaiting the final clearance from the ethics committee before making the survey public. To complete it, please come back in a few days and click the button below.Thank you!
