Time Slice Manipulation in Information Hierarchy.
Abstract
This paper presents theoretical results on a generalized form of partial order, called hierarchical partial order, for enforcing serializability that takes advantage of transaction analysis in database systems. Transaction analysis partitions the database into data partitions that may assume a hierarchy of priorities, such that transactions primarily updating less critical data partitions will not interfere with transactions primarily updating the more critical data partitions, or will do so to a lesser extent than those in conventional systems. This results from the ability for transactions in the system to access different data partitions using different synchronization protocols. The rules governing the different protocols are presented and their corrections with respect to serializability is proven.
