Deductive Data Warehouses: Analyzing Data Warehouses With Datalog (By Example)

This chapter presents the concept of “deductive data warehouses.” Deductive data warehouses rely on deductive databases but use a data warehouse in the background instead of a database. The authors show how Datalog, as a logic programming language, can be used to perform on-line analytical processing (OLAP) analysis on data. For that purpose, a small data warehouse has been implemented. Furthermore, they propose and briefly discuss “Datalog by example” as a visual front-end tool for posing Datalog queries to deductive data warehouses.
