Extended Change Identification System

Parimala N., Vinay Gautam

Abstract

Schema evolution leads to multiple versions of the data warehouse schema. We address the issue of whether the information required by the decision maker is present in some version of the data warehouse or not by checking all the versions for the existence or the absence of the required information. The user specifies the sought information using business terms. We build Delta Ontology which captures the ontology information in terms of mapping between business terms and schema terms. The Delta Ontology is built for the modifications to the schema as it evolves. We propose an algorithm to search for the information in the latest version of E-Metadata and the Delta Ontology. Our algorithm lists all the versions where the information is available giving precedence to finding the information in a single version over across versions. The decision maker is also informed if the information is totally missing.
