Paper Abstract:
|
Most conventional databases in use today are handling crisp and precise data. Fuzziness in databases is a form of multivalued
logic derived from fuzzy set theory to deal with reasoning. Combining database and fuzzy technologies will allow
the specification of imprecise real-world semantics. Active rules, also named Event-Condition-Active rules, have mainly
been used in relational database systems for integrity control and are promising features for XML databases. This paper
proposes a fuzzy active rules system that is built on top of existing XML databases to allow specifications of integrity
constraints and business semantics. This paper describes the language framework that allows users to specify active rules
include fuzzy conditions as well as crisp expressions. Rule logic is mainly described using standard XQuery commands.
Since XML database users are already familiar with XQuery commands, this features greatly enhances the usability of
the language. The paper also demonstrates our design and implementation of the system architecture that allows multiple
rule execution at run time when active rules are triggered by database events. To the best of our knowledge, no other
projects have reported a rule engine that handles fuzzy active rules over XML databases. |
