comment Alternatives to NULL for missing data
@ypercube Generally, following Joe Celko's advice to default to using non-null constraints. Specifically, I would like to use nonnull constraints to avoid many known issues with nulls, e.g. in computation and logical queries, and also to be able to distinguish data that is missing from data that does not exist.
