Inheriting Access Control Rules from Large Relational Databases to Materialized Views Automatically

摘要

A novel approach for automatically inheriting access control rules form large relational databases to materialized views defined on such databases is proposed in this paper, along with main algorithm VSP-Bucket. Our proposal introduces a number of research innovations, ranging from a novel Datalog-based syntax, and related semantics, for modeling and expressing access control rules over relational databases to algorithm VSP-Bucket itself, which is a mea-ningifully adaptation of a well-know view-based query re-writing algorithm for database optimization purposes. A preliminary experimental evaluation and analysis of performance of algorithm VSP-Bucket completes our foremost analytical contribution made in this research.
