A rule-based AOP framework for process rule aspect in business process

Abstract

In recent years, numerous studies have attempted to find and explore issues of a web service oriented business process specification such as. In particular, a business rule is one of the important crosscutting concerns to be separated from a business process. In this paper we present a rule-based AOP framework that Process Rule Aspect(PRA) such as business rule aspects contained in business processes can be effectively separated and executed using a mechanism of business rules itself used at rule engines instead of using the existing programming language based AOP technologies. Moreover, we introduce how separated PRAs through an external rule engine can be represented and evaluated through some examples and how it can be dynamically weaved and executed by providing an implementation example which uses two open source based products. It is difficult to implement inherent characteristics of business rules and to adapt to changes of business process at hard-coded process because mostly they are implemented at the programming language level. However the proposed approach enables business processes to adapt dynamic changes without stopping runtime processes and to provide a better management capability by reason of using business rule technology having high level representation methods.
