A Family of Incomplete Relational Database Models
Summary: Introduces a family of incomplete relational models using value intervals to represent unknowns; intra-table encodes three partial tuple types, and inter-table incompleteness can occur at relation, tuple, or attribute level. All models ensure sound but incomplete query evaluation and adopt a geometric view where each tuple is a set of d-dimensional cubes, with implementation notes and comparisons to prior approaches.
