    A B2B benchmark on top of UMM and TPC-app
    (Pragmatic web – Proceedings of the first international conference on the pragmatic web, 2006, 2006) Hofreiter, Birgit; Huemer, Christian; Mosser, Robert
    The TPC-App is a B2B benchmark implementing a retail scenario. This benchmark specifies a set of web services interactions to test the performance of an application server. Today B2B systems undergo a permanent technological change. There even exist competitive technologies at the same time. From a business perspective it is important that the application systems of the business partners interoperate no matter what technology is applied. In order to measure the effects of using a combination of different technologies for the same B2B scenario, we reverse engineer the TPC-App scenario into a platform independent model following the UN/CEFACT's Modeling Methodology (UMM). The resulting UMM-App benchmark defines a conceptual B2B model that may be implemented by different IT technologies in order to evaluate feasibility and performance.

    Big Data Management and Analysis for Business Informatics - A Survey
    (Enterprise Modelling and Information Systems Architectures - An International Journal: Vol. 9, Nr. 1, 2014) Marchand-Maillet, Stéphane; Hofreiter, Birgit
    Modern communication networks have fueled the creation of massive volumes of data that may be valued as relevant information for business activities. In this paper, we review technologies for enabling and empowering business activities, leveraging the content of this big data. We distinguish between data- and user-related technologies, and study the parallel brought by the overlap of these categories. We show how the trend of Big Data is related to data security and user privacy. We then investigate automated ways of performing data analysis for Business Intelligence. We finally review how groups of users may be seen as a workforce in business through the notion of human computation or crowdsourcing, associated with the notions of trust and reputation. We conclude by discussing emerging trends in the domain.
