IRDS: AN INTEROPERABLE RECURSIVE DATABASE SERVER

THIS RESEARCH DEVELOPS THE ARCHITECTURE FOR AN INTEROPERABLE RECURSIVE DATABASE SERVER (IRDS). THE SERVER COMMUNICATES WITH CLIENTS BASED ON DAL, AN INDUSTRIAL STANDARD ON DATA ACCESS LANGUAGE SUPPORTING HETEROGENEOUS DATABASE ENVIRONMENTS. RECURSIVE VIEWS DEFINED WITH POWERFUL LOGIC RULES ARE SUPPORTED. QUERIES ON RECURSIVE VIEWS WILL BE AUTOMATICALLY TRANSLATED INTO EQUIVALENT DATABASE OPERATIONS ON THE BASE RELATIONS. THE TRANSLATION IS BASED ON PRE-COMPILED INFORMATION OBTAINED FROM THE ANALYSIS OF THE STRUCTURE OF THE RECURSION DURING VIEW DEFINITION. A TOOLKIT AND A PROTOTYPE ARE BEING DEVELOPED AS A FEASIBILITY STUDY.
