Zusammenfassung: | This paper presents the idea of deductive data warehouses. Deductive data warehouses rely on deductive databases but instead of a database in the background a data warehouse is used. The authors show how Datalog (as a logic programming language) can be used to perform OLAP analysis on data. Since data warehouses don't use all the technologies that databases do (locking, transactions, integrity constraints, etc., which are not relevant in this context), some things are different and simpler then when working with deductive databases. The authors demonstrate the idea on an example and the authors show that Datalog rules can be used to perform OLAP analysis on data. |
