A Coreference Service for Enterprise Application Integration using Linked Data

The use of semantic and Linked Data technologies for Enterprise Application Integration (EAI) is increasing in recent years. Linked Data and Semantic Web technologies such as the Resource Description Framework (RDF) data model provide several key advantages over the current de-facto Web Service and XML based integration approaches. The flexibility provided by representing the data in a more versatile RDF model using ontologies enables avoiding complex schema transformations and makes data more accessible using Web standards, preventing the formation of data silos. These three benefits represent an edge for Linked Data-based EAI. However, work still has to be performed so that these technologies can cope with the particularities of the EAI scenarios in different terms, such as data control, ownership, consistency, or accuracy. The first part of the paper provides an introduction to Enterprise Application Integration using Linked Data and the requirements imposed by EAI to Linked Data technologies focusing on one of the problems that arise in this scenario, the coreference problem, and presents a coreference service that supports the use of Linked Data in EAI systems. The proposed solution introduces the use of a context that aggregates a set of related identities and mappings from the identities to different resources that reside in distinct applications and provide different views or aspects of the same entity. A detailed architecture of the Coreference Service is presented explaining how it can be used to manage the contexts, identities, resources, and applications which they relate to. The paper shows how the proposed service can be utilized in an EAI scenario using an example involving a dashboard that integrates data from different systems and the proposed workflow for registering and resolving identities. As most enterprise applications are driven by business processes and involve legacy data, the proposed approach can be easily incorporated into enterprise applications.

Integration of Electronic Commerce and Enterprise Systems

The necessity of EC (Electronic Commerce) and enterprise systems integration is perceived from the integrated nature of enterprise systems. The proven benefits of EC to provide competitive advantages to the organizations force enterprises to adopt and integrate EC with their enterprise systems. Integration is a complex task to facilitate seamless flow of information and data between different systems within and across enterprises. Different systems have different platforms, thus to integrate systems with different platforms and infrastructures, integration technologies, such as middleware, SOA (Service-Oriented Architecture), ESB (Enterprise Service Bus), JCA (J2EE Connector Architecture), and B2B (Business-to-Business) integration standards are required. Huge software vendors, such as Oracle, IBM, Microsoft, and SAP suggest various solutions to address EC and enterprise systems integration problems. There are limited numbers of literature about the integration of EC and enterprise systems in detail. Most of the studies in this area have focused on the factors which influence the adoption of EC by enterprise or other studies provide limited information about a specific platform or integration methodology in general. Therefore, this thesis is conducted to cover the technical details of EC and enterprise systems integration and covers both the adoption factors and integration solutions. In this study, many literature was reviewed and different solutions were investigated. Different enterprise integration approaches as well as most popular integration technologies were investigated. Moreover, various methodologies of integrating EC and enterprise systems were studied in detail and different solutions were examined. In this study, the influential factors to adopt EC in enterprises were studied based on previous literature and categorized to technical, social, managerial, financial, and human resource factors. Moreover, integration technologies were categorized based on three levels of integration, which are data, application, and process. In addition, different integration approaches were identified and categorized based on their communication and platform. Also, different EC integration solutions were investigated and categorized based on the identified integration approaches. By considering different aspects of integration, this study is a great asset to the architectures, developers, and system integrators in order to integrate and adopt EC with enterprise systems.

The Emergence of Partnership Networks in the Enterprise Application Development Industry - A Global Corporation Perspective

Currently, dramatic changes are happening in the IS development industry. The incumbent system developers (hubs) are embracing partnerships with less well established companies (spokes), acting in specific niches. This paper seeks to establish a better understanding of the motives for this strategy. Relying on existing work on strategic alliance formation, it is argued that partnering is particularly attractive, if these small companies possess certain capabilities that are difficult to obtain through other arrangements than partnering. Again drawing on the literature, three categories of capabilities are identified: the capability to innovate within their niche, the capability to provide a specific functionality that can be integrated with the incumbents’ systems, and the capability to address novel markets. These factors are analyzed through a case study. The case represents a market leader in the global IS development industry, which fosters a network of smaller partner firms. The study reveals that temporal dynamics between the identified factors are playing a dominant role in these networks. A cyclical partnership model is developed that attempts to explain the life cycle of a partnership within such a network.

Computer Integrated Business: Theoretische und empirische Analyse der bisherigen Ansätze und zukünftigen Perspektiven

Die Arbeit stellt einen strukturellen Rahmen zur Einordnung sowohl bisheriger als auch zukünftiger organisationstheoretischer und DV-technologischer Entwicklungen zur Umsetzung eines Computer Integrated Business (CIB) bereit. Dazu analysiert sie bisherige Ansätze und zukünftige Perspektiven eines CIB mittels theoretischer und empirischer Bearbeitungsverfahren. Die Notwendigkeit zur Unternehmensintegration ergibt sich aus dem betriebswirtschaftlichen Konzept der Arbeitsteilung, über die das Phänomen der Economies of Scale erschlossen wird. Die Arbeitsteilung wurde zum Gestaltungskonzept in den Fabriken der industriellen Revolution. Komplexe Arbeitsgänge wurden in spezialisierte Teilaufgaben zerlegt und nach Möglichkeit auf maschinelle bzw. technologische Potentiale übertragen. Die Zielsetzung lag zunächst in der Automatisierung des Materialflusses, während der Informationsfluss noch lange Zeit im Hintergrund stand. Mittlerweile ermöglichen leistungsfähige DV-Systeme auch die Automatisierung des Informationsflusses und damit die DV-gestützte Integration des Unternehmens, die den Kern des CIB-Konzeptes darstellt. Das CIB-Konzept wurde Ende der achtziger Jahre am Fraunhofer-Institut für Arbeitswirtschaft und Organisation als Erweiterung des Computer Integrated Manufacturing (CIM) für Industrieunternehmen von Bullinger geprägt, jedoch in seiner Zielsetzung als Modell zur Totalintegration von Unternehmen danach nicht maßgeblich weiterentwickelt. Vielmehr wurden in der Folgezeit überwiegend Teilintegrationslösungen diskutiert, wie z. B. Konzepte zur Integration der Fertigung oder zur Unterstützung der Teamarbeit. Der Aspekt der umfassenden, unternehmensinternen Integration rückte Mitte der neunziger Jahre durch die an Popularität gewinnende Internet-Technologie an den Rand der wissenschaftlichen Diskussion. Erst nach dem Zusammenbruch der ersten Internet-Euphorie und der anschließenden wirtschaftlichen Rezession gewann das Integrationsthema am Anfang dieses Jahrzehnts mit Hinblick auf dadurch mögliche Kostenvorteile wieder an Bedeutung. Die Diskussion wurde jedoch mit starkem technologischem Fokus geführt (z. B. zum Thema Enterprise Application Integration) und Aspekte der Unternehmensorganisation wurden bestenfalls grob, jedoch nicht im Detail diskutiert. Die vorliegende Arbeit bearbeitet die CIB-Thematik umfassend sowohl aus unternehmensorganisatorischer als auch DV-technologischer Sicht und bewegt sich deshalb interdisziplinär zwischen den Wissenschaftsbereichen der Betriebswirtschaft und der Informatik. Die Untersuchung wird vor dem Hintergrund einer sozio-technologischen Unternehmensorganisation geführt, in der DV-technologische Potentiale neben humanen Potentialen zur Erreichung der Unternehmensziele eingesetzt werden. DV-technologische Potentiale übernehmen darin einerseits Integrationsaufgaben und werden andererseits aber selbst zum Integrationsziel. Die Herausforderung für die Unternehmensführung besteht in der Konfiguration des CIB und im Finden eines Gleichgewichts zwischen Arbeitsteilung und Integration auf der einen sowie humanen und technologischen Potentialen auf der anderen Seite, letztendlich aber auch in der Automatisierung der Integration. Die Automatisierung der Integration stellt mit Hinblick auf die durch Umweltveränderungen bedingte Konfigurationsanpassung ein bisher konzeptionell nur ansatzweise gelöstes Problem dar. Der technologischen Integrationsarchitektur sowie den verwendeten Methoden des Prozessdesigns und der Software-Entwicklung kommt bei der Lösung dieses Problems eine hohe Bedeutung zu. Über sie bestimmt sich die Anpassungsfähigkeit und geschwindigkeit des CIB. Es kann vermutet werden, dass eine Lösung jedoch erst erreicht wird, wenn sich die Unternehmensorganisation vom Konzept der zentralen Koordination abwendet und stattdessen an dezentralen Koordinationsmechanismen unter Verwendung ultrastabiler Anpassungsprogramme orientiert, wie sie z. B. in der Biologie bei Insektenkulturen untersucht wurden.

Application of computer-aided facilities management (CAFM) for intelligent buildings operation

Purpose – The purpose of this paper is to investigate the concepts of intelligent buildings (IBs), and the opportunities offered by the application of computer-aided facilities management (CAFM) systems. Design/methodology/approach – In this paper definitions of IBs are investigated, particularly definitions that are embracing open standards for effective operational change, using a questionnaire survey. The survey further investigated the extension of CAFM to IBs concepts and the opportunities that such integrated systems will provide to facilities management (FM) professionals. Findings – The results showed variation in the understanding of the concept of IBs and the application of CAFM. The survey showed that 46 per cent of respondents use a CAFM system with a majority agreeing on the potential of CAFM in delivery of effective facilities. Research limitations/implications – The questionnaire survey results are limited to the views of the respondents within the context of FM in the UK. Practical implications – Following on the many definitions of an IB does not necessarily lead to technologies of equipment that conform to an open standard. This open standard and documentation of systems produced by vendors is the key to integrating CAFM with other building management systems (BMS) and further harnessing the application of CAFM for IBs. Originality/value – The paper gives experience-based suggestions for both demand and supply sides of the service procurement to gain the feasible benefits and avoid the currently hindering obstacles, as the paper provides insight to the current and future tools for the mobile aspects of FM. The findings are relevant for service providers and operators as well.
