A Proof System with Bounded Non-determinism in Database Transformations,iers over only the database part of a state which is a finite structure, we can formalise non-determinism of DB-ASMs by utilising a modal operator [] for an update set or multiset generated by a DB-ASM rule. In doing so, we lay down a solid foundation for the completeness proof of the proof system proposed for DB-ASMs in this paper.

About Semantics, has been achieved in the field. Previous SDKB volumes survey different approaches to semantics in database research and discuss research on database semantics. Most of these research questions are still open.

Answers that Have Integrity, cause of an answer is a minimal excerpt of the database that explains why the answer has been given. An answer has integrity if one of its causes does not overlap with any cause of integrity violation.

A Proof System with Bounded Non-determinism in Database Transformations,his paper we present a proof system for DB-ASMs. It is shown that the proof system for DB-ASMs is sound. As DB-ASMs are restricted by allowing quantifiers over only the database part of a state which is a finite structure, we can formalise non-determinism of DB-ASMs by utilising a modal operator []
