Artifacts represent concrete elements in the physical world that are the result of a development process. Business process modeling bpm is an important, if not essential, activity in developing information systems. Business process agility is part of a broader agility issue, i. In this paper, we motivate the need for aspect oriented concepts in business process modeling languages and propose an aspect oriented extension to bpmn called. In this paper we propose the use of an aspect oriented approach to modularize business process modeling. With all above being true, it can be summarized as how work gets done in. Aspect orientation is an increasingly promising approach to software development.
In computing, aspectoriented software development aosd is a software development technology that seeks new modularizations of software systems in order to isolate secondary or supporting functions from the main programs business logic. Aosd aims to address crosscutting concerns by providing means for systematic identification, separation, representation and composition. Aspectoriented software development aosd is a software design solution that helps address the modularity issues that are not properly resolved by other software approaches, like procedural, structured and objectoriented programming oop. To address these limitations, this paper proposes a new aspect. The architecture of an aspect oriented system is based around a core system plus extensions. It is a structure diagram which shows architecture of the system as deployment distribution of software artifacts to deployment targets. With advances in software design, the vision of bpm models becoming fully executable and. Correctness of aspectoriented business process modeling.
