Abstract: Current needs of E-Commerce transactions require the development of XML database system like relational database systems. Fuzzy concepts are adapted to the field of XML Databases (DB) in order to deal with ambiguous and uncertain data. Incorporating fuzziness into Event Condition Action (ECA) rules would improve the effectiveness of XML DB as it provides much flexibility in defining rules for the supported application. An architecture that specifies how the fuzzy logic based rules are processed in the context of XML database transactions is presented in this paper. The algorithm for implementing fuzzy active rule based triggers for XML is proposed in this paper. The proposed architecture provides new forms of interaction, in support of fuzzy ECA rules between any application programs and the XML database. This paper presents a motivating example that illustrates the use of fuzzy trigger in stock market brokering agency. The testing has been done to compare the performance of fuzzy XML triggers and normal XML triggers. Our testing results show that Fuzzy ECA rule based triggers are providing better output than Normal ECA rule based triggers.

Keywords: XML DB, ECA rules, fuzzy eca rules, fuzzy xquery, fuzzy trigger.
