Boulanger D. Using deductive data bases for complex applications. A pragmatic study. Internal note CNUCE-B4-96-032, 1996.
The paper is focused on pragmatic (programming) aspects of using deductive databases for complex data intensive applications. This includes a comparative study of applying declarative and non-declarative logic programming styles, their influence on run-time efficiency. Two deductive database systems based on LDL++ and XSB systems are discussed. In particular, the paper is based on experience which has been collected exploiting the deductive database System currently running at CNUCE. It consists of LDL++ , which is usesd as a query processor for the DBMS Sybase and the DBMS Oracle. Also, experiments with the most recent version of the XSB System are presented
