Abstract:
This paper presents a solution to check referential integrity constraints and conjunctive
global constraints in a relational multi database system. It also presents the experimental
results obtained by implementing this solution over a PC cluster with Oracle9i DBMS.
The goal of those experimentations is to measure the time spent to check global
constraints in a distributed systems. The results show that the overhead induced by our
distributed constraint checking is reduced by 50% compared to a centralized checking of
constraints.
