A Logic Framework to Support Database Refactoring

摘要

We propose a formal framework for database refactoring, analyzing both the changes to the database schema, and their impact on queries. The framework defines a logic model of changes, and views the database refactoring process as an agent based one. The agent tries to discover and resolve inconsistencies, and it is modeled as a problem solver capable to perform changes triggered upon the detection of database schema anomalies. The framework can be considered a first step towards the automation of the database refactoring process.
