    The globalization of industrial enterprises leads to problems caused by the heterogeneity of hard- and software. To overcome these problems, distributed platforms can be used. Yet, much work remains to be done on distributed platforms before they actually can meet industrial needs. For example, there is no standardized mechanism for asynchronous data transfer and no possibility to transmit so-call... View full abstract»

    One of the most important CORBA services defined by the OMG is the Object Transaction Service (OTS) which augments the CORBA object model with the notion of distributed transactions. The implementation design of the OTS is critical for the service to be really effective for applications. A good design suggests that the OTS should be part of the ORB (object request broker) itself rather than on top... View full abstract»

    We propose electronic contract negotiation-a sub-part of the more general area of electronic commerce-as an example application for mobile agents. We start by presenting a set of requirements that an application should fulfil in order to take advantage of mobile agents and show that not all distributed applications meet these requirements. We then present contract negotiation, an example of an app... View full abstract»

    Meta-modeling is critical to the success of distributed object environments such as CORBA and ActiveXI DCOM. However, there is a surprisingly large variation in the nature of the meta-models (and meta-meta-models) that have been proposed for such environments. This paper investigates this phenomenon by examining the basic tenets of meta-modeling in the context of distributed object environments, a... View full abstract»

    Current approaches for service mediation, such as trading, do not provide means for a long-term binding of services. They do not ensure that certain services are provided and that the desired service properties are fulfilled. Moreover, a server may withdraw a service offer at any time. For the integration of external services into an enterprise internal service market, it is necessary to guarantee... View full abstract»

    Previous work on long-running transactions for multi-database environments relaxes the isolation requirement of conventional ACID transactions. However, most of that work does not provide mechanisms to explicitly enforce isolation. This paper proposes a framework in which long-running transactions can specify global predicate-based locks to enforce limited forms of isolation between selected trans... View full abstract»

    CORBA enables objects to interact in a transparent manner according to location and heterogeneity. However, this kind of platforms lack mobility functions. That is why the author proposes a solution based on a generic implementation of CORBA's LifeCycle service. The mechanism relies on intermediary objects that are used to encapsulate mobility management View full abstract»
