Incomplete Information and Certain Answers in General Data Models
Summary: Introduce a general framework using semantics-based orderings to model degrees of incompleteness, showing relational and XML certain answers as instances of a single concept. Apply it to explain naive evaluation, settle XML existence questions, expose limits of prior null-ordering models, subsume relations/documents, and derive complexity and data-exchange results.
