Abstract
Enterprise resource planning (ERP) is a business process management system in which integrated applications are used to manage business processes in a shared data environment. ERP systems usually deal with the two types of business processes, i.e., exchange and conversion. In the exchange process, economic resource, such as product, exchanges to another economic resource, such as the sales process. In a conversion process, an enterprise consumes resources in order to produce new resources, such as the distribution process. Generally, the communication between ERP applications, based on the conversion and exchange processes, is accomplished through Web services. In this context, the implementation of Web services in ERP systems is a complex task. To manage this, the business process model and notation (BPMN) are frequently utilized to simplify the development of ERP applications. However, state-of-the-art BPMN approaches usually deal with the modeling of exchange processes without considering the conversion process. Furthermore, the model transformation solution to automatically generate Web services from the BPMN models are hard to find in the literature. Therefore, in this paper, a novel framework is proposed that supports the modeling of both exchanges as well as conversion processes through BPMN. Particularly, a modeling approach is introduced to represent the ERP processes through BPMN concepts. Subsequently, the rules are developed to convert source BPMN models into target Service-oriented architecture Modeling Language (SoaML) models. Finally, transformation rules are developed to generate fully functional executable Java Web services from SoaML models. As a part of the research, a complete open-source BPMN to Web services transformation (B2W) tool is developed to automatically generate the Web services from the high-level BPMN models. The proposed framework is validated through multiple case studies. The experimental results prove that the proposed framework accurately generates Web services from the BPMN models, which eventually helps in developing the ERP systems with simplicity.
Highlights
Business models are economic models that describe the way and reasons why and how the organization share values
The model transformation solution to automatically generate web services from Business Process Model and Notation (BPMN) models is hard to find in the literature
In order to obtain the complete Java code for the web services for exchange and conversion processes, Both M2M and M2T transformation is applied on BPMN and Service-oriented architecture Modeling Language (SoaML) model
Summary
Business models are economic models that describe the way and reasons why and how the organization share values. The proposed work includes a fully automated approach to generate java web services code from exchange and conversion business processes that are modeled in BPMN. In order to obtain the complete Java code for the web services for exchange and conversion processes, Both M2M and M2T transformation is applied on BPMN and SoaML model. Exchange and Conversion process BPMN models are transformed into a SoaML model, which contains the services, constructs as service architecture and the connections between them are represented using connecting objects such as realization and usage for web service specification. Major components of transformation engine are Main Interface, ATL and Acceleo Transformation and BPMN model, SoaML model and Java web services code for selected business processes of ERP system as transformation output artifacts. Use connecting element is mapped to Data Parameters with its visibility mode. Attribute is mapped to Class Attributes with its visibility mode. Operation is mapped to Class Operation with its return type and visibility mode. Operation Parameter is mapped to Class Operation Parameter with its name and parameter name
