Using Witness Generators to Support Bi-directional Update Between Object-Based Databases
Summary: Shows incremental uni-/bi-directional update for object DBs with SPJ+OID-invention ILOG is, without auxiliaries, essentially graph-isomorphism hard. Introduces "witness" auxiliary data to bring uni-directional update to LOGSPACE and gives a limited "witness-generator" procedure enabling bi-directional update in LOGSPACE.
