Using NoSQL stores as storage layer for the execution of declarative query processing using XQuery provides a highlevel interface to process data in an optimized manner. The term NoSQL refers to a plethora of new stores which essentially trades off well-known ACID properties for higher availability or scalability, using techniques such as eventual consistency, horizontal scalability, efficient ...

This paper intends to remind communication scientists that the indirect effect as estimated in mediation analyses is a statistical synonym for omitted variable bias (i.e. confounding or suppression). simple fact questions interpretability of statistically significant ‘indirect effects’ when using observational data: social reality, all variables correlate with each other some extent – so-called...

We study, in the context of object/relational mapping tools, the problem of describing mappings between inheritance hierarchies and relational schemas. To this end, we introduce a novel mapping model, called MORM+HIE , and investigate its mapping capabilities. We first show that MORM+HIE subsumes three well-know basic representation strategies for mapping a hierarchy to relations. We then show ...

We present a novel framework and algorithms for the analysis of Web service interfaces to improve the efficiency of application integration in wide-spanning business networks. Our approach addresses the notorious issue of large and overloaded operational signatures, which are becoming increasingly prevalent on the Internet and being opened up for third-party service aggregation. Extending upon ...

Enterprise systems and architectures are a field of significant research, especially in regard to service-oriented architectures and web services. Web services propose great benefits and are often suggested as the new paradigm for building distributed applications and systems, but they are becoming more and more complex and consequently less understandable for humans. The web development commun...
