    Semantic data integration: overall architecture

    The information has always been a valuable patrimony for the information systems that every company tries to capitalize as much as possible. With the web, the amount of information is increased and several problems arise for instance for the safety of the exchanged data but also to the semantic heterogeneity: the same information is very often represented in different ways in different information systems. In this paper we present an architecture of interchange of data both within the same information system and among different information systems founded on the ontologies in order to overcome the problem list of the heterogeneity. Ontologies, today, they seem to be the best tool useful to resolve the problem of heterogeneity, but that has not now been exploited fully

    Semantic Integration of Information Systems

    In the previous years Information System manage only information inside the company, today a company may search and manage information of the other companies. In this scenario the problem of communication between Information Systems is of the highest importance. Up to the present moment, several types of integration have been used but all were founded on the agreement (about data to share and the exchange format) between the interested Information Systems. Today, thanks to the new technologies, it is possible that an Information System uses data of another Information System without a previous agreement. The problem is that, often, the Information System may refer to the same data but with different names. In this paper we present a methodology that, using ontology, and thus the intrinsic semantic of each data of the Information System, allow to create a global ontology useful to enable a semantic communication between Information Systems

    Evaluating potential benefits on the use of RFID,EPCglobal, and ebXML in the pharmaceutical supply chain

    This paper attempts to evaluate the impact of Radio Frequency Identification (RFID) technology, EPCglobal and ebXML on some business processes that are critical to the success of the pharmaceutical supply chain. Particular attention is focused on the wholesaler because it represents a particular stress point in terms of constraints and product flow. A quantitative and qualitative analysis of some current (AS IS) supply chain processes was performed on a big pharmaceutical wholesaler. It allowed us to identify some critical factors in the main business processes. In order to guarantee an efficient item-level tracing system in the whole supply chain, a re-engineering procedure has been defined exploiting an approach based on the combined use of RFID, EPCglobal, and ebXML. The Key Performance Indicator (KPI) method has been chosen to carry out the analysis of the potential benefits by using an empirical method based on the Living Laboratory approach. This rigorous experimental approach, performed in a controlled test environment, allowed us to derive a realistic estimate of the selected performance indicators for the reengineered (TO BE) model

    B2B Interoperability using Business-Driven Integration: Conceptual Framework and Case Study

    No full text
    The interoperability among companies and the business-to-business (B2B) message exchange are key aspects of the growth of businesses: in the next years the companies that are able to cooperate with each other will be winners. The use of B2B messages modifies a company’s method of operation and, of course, its internal business process. In this paper, we propose a conceptual framework to solve the two types of problems that arise in the B2B field: one is more methodological, aimed at choosing guidelines oriented to the integration of business processes and the definition of business messages; the other is more technological, aimed at choosing an infrastructural solution more suitable for the development of message exchanges. The paper also defines a case study in order to show the feasibility of the conceptual framework. Using a specific case study, the paper will show the methodological and technological choices and how ontologies are the glue for different standards and notations involved in business-driven integration problems. Using BPMN notation, we design in this paper a business process that involves different business messages. The paper also presents a REST implementation of the business message exchange
