ABSTRACT:
Systems and methodologies are provided for enforcing a set of conditions such that prior to a commit stage of a transaction, a space availability for a particular page can be typically assured (e.g., that transactions operating on various copies of the page do not consume all of storage space on that page), and reorganization of data around the page is mitigated (e.g., that a transaction need not move data around the page for purpose of merging various copies.) A page aggregator and a heap manager can facilitate operations of concurrent transactions at a subpage level (e.g., a row level), during such modifications of a data base by multiple users.
