A decentralized and service‐based solution for data mediation: the case for data providing service compositions

Abstract

The last few years have seen an increase in the use of e-services as a natural consequence of the service-based economy growth. However, the distributed nature of services can raise several heterogeneity problems that can hamper the widespread adoption of service-oriented architectures (SOA). In this paper, we are interested in data heterogeneity problems that can occur when using composite services. We propose a service-based approach for automatically inserting appropriate mediation services in service compositions to resolve structural heterogeneities in their data flow. This mediation is ensured through a special kind of Web services called data mapping Web services. In addition, in order to be in agreement with the distributed nature of the Web, we propose a decentralized solution to publish/discover these services. We demonstrate how our approach applies to the data structural heterogeneity problem in data providing service compositions as a particular data heterogeneity case. Provided experimental results show that our approach is efficient in realistic situations.

Reusability and discovery models in software systems: a systematic literature review.

“…The number of devices, their heterogeneity, distributed deployments together with virtual components providing a great number of reusable services make this domain a perfect target scenario to develop discovery solutions. Apart from the CPS domain, blockchain (Zhao et al 2018), modeling approaches (Jose et al 2020), and data management techniques (Sellami et al 2015), among other examples, have emerged as new opportunities for discovery models.…”

“…In (Sellami et al 2015), the authors propose a service-based solution to eliminate structural heterogeneities in a composite data providing (DP or DaaS) service data flow by the discovery of a special type of mediation web service named data mapping (DM) service. Data mapping services provide the data provided The approach in (Verma & Srivastava 2018) describes a service registry framework that makes use of an Extensible Messaging and Presence Protocol (XMPP) based model to maintain a service registry for mobile environments.…”

“…The paper by Mohamed Sellami et al titled ‘A Decentralized and Service‐Based Solution for Data Mediation: The case for Data Providing Service Compositions’ deals with Web services and semantic mediation and addresses the problem of data heterogeneity in service composition. The authors propose a service‐based approach for automatically inserting appropriate mediation services in Data‐as‐a‐Service compositions to resolve structural heterogeneities in their data flow.…”
