Component framework supporting inter-company cooperation 支持公司间合作的组件框架

{"title":"Component framework supporting inter-company cooperation","authors":"Klement J. Fellner, K. Turowski","doi":"10.1109/EDOC.1999.792060","DOIUrl":"https://doi.org/10.1109/EDOC.1999.792060","url":null,"abstract":"The Internet has created a tremendous opportunity to conduct business electronically. Innovative business concepts, like virtual enterprises, supply chain management, or one-to-one marketing, as well as advanced competitive strategies encompassing these business concepts, like mass customization, may be followed-up much more efficiently. However, competitive strategies like mass customization require sophisticated information infrastructures to support the indispensable business to business electronic commerce-even for small and medium enterprises taking part in a virtual enterprise that pursues mass customization. Especially electronic data interchange (EDI), which is understood as a means to exchange business data, is crucial to set up and maintain virtual enterprises. Thus, there is high demand on inexpensive and easily employable software that allows platform-independent exchange of business data between companies. We present an approach to a component (application) framework that aims to achieve this goal. By using the extensible markup language (XML) as an important cross-platform technique, together with common business communication standards, we show how the border of heterogeneous (distributed) application systems can be overcome. With this, the business communication protocol is set up. Taking this protocol as a basis, we further present a component framework, which is implemented using the JavaBeans technology that supports efficient inter-company communication. In addition, we show how this approach may further develop to a means for inter-company coordination.","PeriodicalId":365462,"journal":{"name":"Proceedings Third International Enterprise Distributed Object Computing.

A CORBA based framework for trusted E-commerce transactions 用于可信电子商务事务的基于CORBA的框架

{"title":"A CORBA based framework for trusted E-commerce transactions","authors":"K. Arshad, Yacine Atif, M. Siyal","doi":"10.1109/EDOC.1999.792046","DOIUrl":"https://doi.org/10.1109/EDOC.1999.792046","url":null,"abstract":"Business via the Internet is becoming very popular. A number of organizations doing business in the traditional way are extending to do business over the World Wide Web. This not only results in reaching a very large number of customers in a cost-effective way but also makes business transactions fast and efficient. Most business-to-business deals are done through value-added networks (VANs) but, for general consumer-to-business deals, the Internet provides a powerful base. However, customer confidence in Internet commerce needs to be further strengthened before large-scale Internet purchasing becomes a reality. In recent years, we have seen the emergence of cryptographic techniques to provide secure transactions, but security alone is not enough, unless the transacting parties also trust each other. Hence, the main ingredient missing is trust. Many attempts have been made to provide secure and trust-providing protocols but few have seen any practical use. In this paper, we show how trust can be provided through a network of trust service providers (TSPs). We provide a set of trust services of a very basic nature which can be deployed through such a network. Our solution is implemented in the form of distributed objects on a CORBA-based platform. The clients accessing the trust services are written as Java applets.","PeriodicalId":365462,"journal":{"name":"Proceedings Third International Enterprise Distributed Object Computing.

We present all its architectural properties and functional features.

The integration of product and process models in a unified data model could provide the means by which information could be shared across a manufacturing enterprise throughout the system lifecycle from design to production. Recently, attempts have been made to integrate these two separate views of systems through identifying common data models. This paper relates description-driven systems to multi-layer architectures and reveals where existing design patterns facilitate the integration of product and process models and where patterns are missing or where existing patterns require enrichment for this integration. It reports on the construction of a so-called description-driven system which integrates product data management (PDM) and workflow management (WfM) data models through a common meta-model.","PeriodicalId":365462,"journal":{"name":"Proceedings Third International Enterprise Distributed Object Computing.

Based on the CORBA standard, Eternal provides object replication not only for fault tolerance but also for live software upgrades, as well as resource management facilities. Through the use of interceptors, Eternal renders the object replication transparent to the application, as well as to the ORB and to the operating system. Thus, Eternal works with commercial off-the-shelf CORBA ORBs and standard unmodified operating systems. Eternal handles the difficult issues of object replication, fault tolerance, live upgrades and resource management, thereby allowing the application programmers to focus on the applications.","PeriodicalId":365462,"journal":{"name":"Proceedings Third International Enterprise Distributed Object Computing.

An approach to making CORBA support equivalence relationships 一种使CORBA支持等价关系的方法

The paper introduces a new type relationship called an equivalence relationship which concerns functionality compatibility rather than interface signature compatibility when determining substitutability between two service versions. To support this kind of relationship, parts of the CORBA invocation model will be extended to allow information of equivalent service versions to be discovered at run time from the augmented CORBA Interface Repository. A client request to an old service will then be dynamically and transparently composed as a new-version invocation to a new-version service. The proposed extensions will be useful to provide compatibility not only between versions of the same service but also between two distinct services that have equivalent functionality.","PeriodicalId":365462,"journal":{"name":"Proceedings Third International Enterprise Distributed Object Computing.

An ODP enterprise specification of customer service management for connectivity services 连接服务的客户服务管理的ODP企业规范

Introducing CSM in the service provider's environment includes communicating and interacting with its service management. Considering the complexity of service management, the goal of this paper is to logically separate CSM and service management, from an enterprise point of view, by identifying specific CSM roles which describe the functions of service management that are relevant for CSM. By using the concepts of roles and associations, we abstract from the details of the underlying service management and identify the requirements that have to be met by the service management. The specific CSM roles and associations are formalized using the terms and concepts of the ODP (open distributed processing) enterprise viewpoint specification in order to ensure that the resulting specification can be applied to a wide range of scenarios. The instantiation of the proposed approach within a real-life scenario shows the applicability and the benefits of our approach.","PeriodicalId":365462,"journal":{"name":"Proceedings Third International Enterprise Distributed Object Computing.

CLF/Mekano: a framework for building virtual-enterprise applications CLF/Mekano:构建虚拟企业应用程序的框架

Unlike other infrastructures of the same class, such as CORBA or DCOM, coordination in CLF/Mekano is built-in at the lowest level, namely at the inter-component communication protocol level, and not as a side service (such as the event, transaction or negotiation services of Corba). Although the CLF protocol is \"lightweight\" (it relies on very few concepts and only 8 communication \"verbs\"), it makes the design and implementation of components more complex, but also more valuable if it can be reused. The Mekano library has been developed in order to deal with this complexity, targeting reusability. It provides ready-to-use generic classes of customizable components, as well as useful component parts which can be reassembled according to application specific needs. Of course, further layers of domain-specific libraries (so called business object libraries), can then be developed on top of Mekano, to provide ready-to-use components dedicated to specific business needs (in the line of Enterprise Java Beans).","PeriodicalId":365462,"journal":{"name":"Proceedings Third International Enterprise Distributed Object Computing.
