MigraSOA: Migration of legacy web applications to service oriented architectures (SOA)

Business Process Execution From the Alignment Between Business Processes and Web Services: A Semantic and Model-Driven Modernization Process

“…d. Service orchestration code generation. The service orchestration layer is obtained by a model weaving process which weaves the BPMN and the BP-WS model obtained in step (c) [15]. The result of this weaving is a new model denominated Extended BPMN Model.…”

“…As previously mentioned, this paper focuses on step (c) in Figure 1 where an alignment process is designed using a semantic service discovery algorithm. In this step (c), two main limitations identified in previous work [13]- [15] and introduced in section I have been overcome: i) the alignment process core, the semantic algorithm, proposed in [14], [66] compared directly the labels of the business process tasks with the web service method signature, without taking into account additional relationships like number of common synonyms or main name in synonyms which could be measured; ii) there were not specific tools with an enough high abstraction degree to support the alignment information obtained. The former has been solved by extending the semantic algorithm presented in [32] so that a new algorithm has been introduced in the approach.…”

“…In this sense, Migra-SOA defines model transformations to weave the business processes defined by BPMN models, extending them with information on how to invoke each specific web service (services aligned at MigraSOA phase (c)). This BPMN models extension has been previously performed using the same case study presented in the current work and can be consulted in [15]. Note that, invoking SOAP web services from the BPMN model extension is carried out using synchronous communication by means of their well-defined interfaces (WSDL descriptions).…”

“…Therefore, the available information is wide and difficult to compare, and hence the matching process is error prone, which makes more obvious the need of an automatic alignment processes to ease the management of both internal service repositories and external services. In this context, the MigraSOA project, based on Model-Driven techniques, was proposed to modernize and adapt the software architectures of LWAs to SOAs [13]- [15]. Specifically, an automatic semantic process was used to automate the migration of software.…”

An operational support approach for Mining Unstructured Business Processes

“…Here, operational support approaches perform well with SBP, while they still a challenging task for UBP. In this respect, the [2,3,4,5,6] demonstrate the still encountered issues related to the UBP operational support application. This is justified by their unpredictability, flexibility, and complexity.…”
