Normalizing Incomplete Databases
Summary: Formalizes semantics and normalization theorems for incomplete databases with disjunctive complex objects (set/bag), yielding programming primitives to enumerate the encoded possibilities. Introduces partial normalization and a streaming normalization algorithm that produces possibilities one-by-one in linear space (vs prior exponential), implemented in DBPL with substantial space/time improvements.
