Book Description
Inhaltsangabe:Abstract: Common Object Request Broker Architecture (CORBA), a standard from the Object Management Group (OMG), defines a vendor-independent architecture and infrastructure for distributed systems. Further CORBA species a client-server platform as well as an object-oriented programming model for distributed computing.The Object Request Broker (ORB) implements the part of CORBA which manages communication and data exchange between objects. CORBA-based applications often have to communicate with ORBs from different vendors. Therefore testing the interoperability is one important point in this work. Six actually available ORB implementations are shown and compared at given features. If a problem has to be solved with CORBA, it is necessary to choose the best ORB implementation for that purpose, because they differ often at significant points. Important details for decision are Standard Conformity, Robustness, Functionality as well as Functional Range or Interoperability. Exactly these properties are to be examined in this work. The investigation is performed on six, at the web available ORBs indeed Jacorb 1.4 beta 2, Orbacus 4.1.0, Orbix E2A 2.0, OpenORB 1.2.0, J2SE ORB 1.4.0 as well as TAO 1.2.1 all in their most actual released version. Additionally to these properties the correct implementation of the most important CORBA Services is checked. They are Event Service, Notification Service, Name Service and Transaction Service. The ORBs are compared at this given properties.It shows that the ORBs differ very much from each other and that the CORBA Services are often implemented incorrectly. Further a high costly implementation is no guarantee for best quality at all points. The evaluation shows that a freely available ORB can be as good as or better than a commercial one.

Book Description
The 3rd Eastern European Conference on Advances in Databases and Information Systems (ADBIS’99) took place on 13-16- September 1999, in Maribor, Slovenia. It was organized in cooperation with ACM SIGMOD, the Moscow chapter of ACM SIGMOD, Slovenian Society Informatika, and the Slovenian Ministry of Technology. The aim of the ADBIS series of conferences is to provide a forum for the exchange of scientific achievements and experiences using innovative methods and approaches between the research communities of Central and Eastern Europe and the rest of the world in the area of databases and information systems. The 1999 conference continues the series of ADBIS events held in Moscow, St. Petersburg, and Poznan. The ADBIS steering committee has the ambition to make the ADBIS conference the premiere database and information systems conference in Central and Eastern Europe, to increase interaction and collaboration between researchers from East and West, and to provide an internationally recognized forum for the presentation of research and experiences in all aspects of modern database technology and information systems. To achieve these goals an international program committee selected 26 full research papers in a rigorous reviewing process from a total of 94 submissions from 33 different countries. This high number of submissions from so many different areas shows the truly worldwide recognition of and interest in the ADBIS series.

Book Description
In today's changing world, enterprises need to survive in an ever volatile competitive market environment. Their success will depend on the strategies they practice and adopt. Every year, new ideas and concepts are emerging in order for companies to become successful enterprises. Cross Border Enterprises is the new 'hot' topic arising in the business process world at present. Many terms have been coined together and are being driven in the popular business press to describe this new strategy of conducting business, ie. Extended Enterprise (Browne et al. , 1995; O'Neill and Sacket, 1994; Busby and Fan, 1993; Caskey, 1995), Virtual Enterprise (Goldmann and Preiss, 1991; Parunak, 1994; Goranson, 1995; Doumeingts et al. , 1995), Seamless Enterprise (Harrington, 1995), Inter-Enterprise Networking (Browne et al. , 1993), Dynamic Enterprise (Weston, 1996) and so on. Many people have argued that they mean the same thing, just using different words. Others feel they are different. But how different are they? In this paper the authors will present some basic lines required from this new strategy for conducting and coordinating distributed business processes (DBP), as well as trying to clarify the particularities of two of the widest spread terms related to it: Virtual and Extended Enterprise. 2 CLUSTERS OF PRESSURES The business world currently faces an increased trend towards globalisation, environmentally benign production and customisation of products and processes, forcing individual enterprises to work together across the value chain in order to cope with market influences.

Book Description
Proceedings of a July 2001 conference, covering all aspects of dependability in classical and networked computer systems, as well as topical areas in IT. There is a special focus on safety and security issues in embedded, multimedia, and Internet applications. Papers are in sections on modeling, algorithms, software demos, replication, software robustness, survivability and security, wireless and mobile communications, real-time, testing and runtime error detection, models for fault tolerance, hardware architecture and design, group-oriented systems, and practical experiences. Specific topics include model- based synthesis of fault trees from MATLAB, a dynamic replica selection algorithm for tolerating timing faults, constructing self- testable software components, and intrusion-tolerant group management in enclaves. This volume lacks a subject index. c. Book News Inc.
