Abstract:
To achieve a precise goal of components on different platforms that are presented the some components in order to co-operate with one another over a communication network. The component should be able to access services provided through remote, location transparent service in vocations.The major role of component-based method is represent an ideal framework for component-driven in client/server computing. One of the good implementation examples of broker architecture is Common Object Request Broker Architecture (CORBA). The component based technologies discuss the proposal of distributed object of CORBA which is the Object Management Group’s (OMG).This paper proposes the broker architecture as CORBA has distributed system that can be demonstrated by client-server architecture which practices the base for multi-tier architecture.

Abstract:
This paper describes an automated query discovery system for retrieving common characteristic knowledge from a database in a distributed computing environment. The paper particularly centers on the problem of discovering the common characteristics that are shared by a set of objects in a database. This type of commonalities can be useful in finding a typical profile for the given object set or outstanding features for a group of objects in a database. In our approach, commonalities within a set of objects are described by database queries that compute the given set of objects. We use the genetic programming as a major search engine to discover such queries. The paper discusses the architecture and the techniques used in our system, and presents some experimental results to evaluate the system. In addition, for the performance improvement, we built a distributed computing environment for our system with clustered computers using the Common Object Request Broker Architecture (CORBA). The paper briefly discusses our clustered computer architecture, the implementation of distributed computing environment, and shows the overall performance improvement.

Abstract:
Abstract:Exchanging and integration of patient data across heterogeneous databases and institutional boundaries offers many problems. We focused on two issues: (1) how to identify identical patients between different systems and institutions while lacking universal patient identifiers; and (2) how to link patient data across heterogeneous databases and institutional boundaries. To solve these problems, we created a patient identification (ID) translation model and a dynamic linking method in the Common Object Request Broker Architecture (CORBA) environment. The algorithm for the patient ID translation is based on patient attribute matching plus computer-based human checking; the method for dynamic linking is temporal mapping. By implementing these methods into computer systems with help of the distributed object computing technology, we built a prototype of a CORBA-based object framework in which the patient ID translation and dynamic linking methods were embedded. Our experiments with a Web-based user interface using the object framework and dynamic linking through the object framework were successful. These methods are important for exchanging and integrating patient data across heterogeneous databases and institutional boundaries.

Abstract:
From design and manufacturing to electronic commerce, coordinating business activities in engineering applications requires accessing data and software from distributed sources. The Common Object Request Broker Architecture (CORBA) of the Object Management Group emerged in the 1990’s as a standard for access to distributed software components. Since that time, the standard has matured significantly, providing advanced features for event notification and transaction processing. At the same time, Java-based technology for distributed object computing has also emerged, from Remote Method Invocation to Enterprise JavaBeans, Jini Connection Technology, JavaSpaces, Java Messaging Service, and Java Transaction Service. Sorting through the options available for the use of such tools can be a difficult task. This paper provides an overview of CORBA and Java technology for distributed object computing. A comparison of these different technologies is presented, discussing the similarities and differences, as well as the way in which such tools can be used together for distributed access to the types of software and data components that are needed for the construction of distributed engineering applications. Future directions for the use of such tools are also identified.

Abstract:
Large business organizations with enterprise wide systems have followed an ad hoc incremental growth pattern. They are either monolithic, that are difficult to replace and maintain, or are components with little or no interoperability between them. Such systems suffer from lack of uniformity and definition in their information technology infrastructure. To migrate from this state, to systems that are extensible, interoperable and non-redundant in functionality it is very important to focus on the architecture. We use the healthcare enterprise system as a case study for the purpose of this thesis. It is indeed difficult, if not impossible to construct the overall architecture of the system without identifying the individual components of the system. Hence we follow an incremental methodology in identifying and developing each component. One such component is Order management, which is an essential component of a healthcare information system that offers enterprise wide functionality.

Abstract:
Component Based Development has emerged as economical, reusable, scalable way of developing enterprise as well as embedded software applications. Testing distributed component based systems is difficult when third party components are being used in the development. Many testing methodologies that have been proposed for testing object oriented programs in the literature are being imported into component domain directly or by tuning them. But testing components involves much manual work due to the lack of information of the component. Middleware architectures like, DCOM(Distributed COM), Jini and CORBA(Common Object Request Broker Architecture) are being used in developing the distributed component applications in different vertical domains. In this thesis, a language- Distributed Object Testing Language(DOTL) for specifying the testing process and generation of distributed testing environment for CORBA based applications has been proposed. The language captures required semantics for specifying dummy servers, clients, controlling the testing process, generation of test cases, activating and deactivating objects. Many existing testing techniques can be specified using the semantics provided by the language. Faults occurring in distributed object systems, in addition to the functional errors, can be identifiable using the tool. The language provides abstract types object, argument to specify variables in the testing environment, and operations dealing with these variables to conducts necessary tests. The DOTL has been implemented on MICO(Mico Is CORBA) orb on Linux OS, with mapping of DOTL to CORBA C++.

Abstract:
Today’s software engineering and application development trend is to take advantage of reusable software. Much effort is directed towards easing the task of developing complex, distributed, network based applications with reusable components. To ease the task of the distributed systems’ developers, one can use middleware, i.e. a software layer between the operating system and the application, which handles distribution transparently. A crucial feature of distributed server applications is high availability. This implies that they must be able to continue activity even in presence of crashes. Embedding fault tolerance mechanisms in the middleware on top of which the application is running, offers the potential to reduce application code size thereby reducing developer effort. Also, outage times due to server crashes can be reduced, as failover is taken care of automatically by middleware. However, a trade-off is involved: during periods with no failures, as information has to be collected for the automatic failover, client requests are serviced with higher latency. To characterize the real benefits of middleware, this trade-off needs to be studied. Unfortunately, to this date, few trade-off studies involving middleware that supports fault tolerance with application to realistic cases have been conducted. The contributions of the thesis are twofold: (1) insights based on empirical studies and (2) a theoretical analysis of components in a middleware equipped with fault tolerance mechanisms. In connection with part (1) the thesis describes detailed implementation of two platforms based on CORBA (Common Object Request Broker Architecture) with fault tolerance capabilities: one built by following the FT-CORBA standard, where only application failures are taken care of, and a second obtained by implementing an algorithm that ensures uniform treatment of infrastructure and application failures. Based on empirical studies of the availability/performance trade-off, several insights were gained, including the benefits and drawbacks of the two infrastructures. The studies were performed using a realistic (telecommunication) applicationset up to run on top of both extended middleware platforms. Further, the thesis proposes a technique to improve performance in the FT-CORBA based middleware by exploiting application knowledge; to enrich application code with fault tolerance mechanisms we use aspect-oriented programming. In connection with part (2) the thesis models elements of an FT-CORBA like architecture mathematically, in particular by using queuing theory. The model is then used to study the relation between different parameters. This provides the means to configure one middleware parameter, namely the checkpointing interval, leading to maximal availability or minimal response time.

Immersive, interactive, and collaborative distributed applications, due to their real time and multi-platform characteristics, require a monitoring structure of their functionalities during the development period, which is not fully available in the current monitoring systems, which are usually specific of the languages and platforms in which they are made available. Monitoring systems that require synchronism of distributed objects during the processing is a complex task. Especially in distributed systems from multi-projection where timing is critical to its operation. It is often difficult to check the correct execution of the system. It might be useful for developers and users of such systems to have the ability of identifying, for example, if the reason for the system delay is due to the abusive use of a resource or due to programming mistakes; the identification of which object has crashed, compromising the system as a whole. Distributed object systems, also known as SOA (Service Oriented Architecture), generally use middleware of the broker type in their infrastructure and can have a dynamic number of connected clients or servers when running. There are, in the literature, several tools for the monitoring of performance, resources, debugging, and support, among others, of such systems. Nevertheless, the tools available in the literature are limited to programming languages or platforms that are able to process the monitoring agents related to them. In this work, a tool for the monitoring of distributed object systems is proposed, based on communication described in XML documents, which allows language and platform independence in the such systems development. A structure for the design of tools for the monitoring of distributed object systems is proposed, based on communication described in XML documents, which allows language and platform independence in the such systems development. In addition to the structure that is theoretically founded, the conception of a tool is structured in the manner described and proven in monitoring data from a case study.
Aplicações Distribuídas Imersivas, Interativas e Colaborativas, dadas suas características de tempo real e multiplataformas, demandam uma estrutura de monitoramento de suas funcionalidades, não plenamente disponíveis nos sistemas atuais de monitoramento, em geral específicos das linguagens e plataformas em que são disponibilizadas. Monitorar sistemas que necessitam de sincronismo no processamento de objetos distribuídos é uma tarefa complexa. Principalmente em sistemas distribuídos e de multiprojeção, onde o sincronismo é fundamental para seu funcionamento. Muitas vezes, é difícil apurar o correto funcionamento dos mesmos. Pode ser útil a desenvolvedores e usuários de tais sistemas a capacidade de se identificar, por exemplo, se a lentidão do sistema está sendo ocasionada por: uso abusivo de um recurso; por um erro na programação de um objeto ou; a identificação de qual objeto travou, comprometendo o sistema como um todo. Sistemas de objetos distribuídos, também conhecidos como SOA (Service Oriented Archtecture), geralmente utilizam mediadores do tipo broker em sua infraestrutura e podem ter um número dinâmico de clientes ou servidores conectados quando estão em execução. Existem na literatura diversas ferramentas destinadas ao monitoramento de performance, recursos, depuração, auxílio, manutenção de tais sistemas, etc. Porém, as ferramentas encontradas na literatura são restritas a linguagens ou plataformas que possam processar os agentes de monitoramento vinculados às mesmas. Neste trabalho, é proposta uma estrutura para a concepção de ferramentas para o monitoramento de sistemas de objetos distribuídos baseados em comunicações descritas em documentos XML, o que permite independência de linguagem ou plataforma na concepção de tais sistemas. Além da estrutura que é teoricamente fundamentada, a concepção de uma ferramenta nos moldes estruturados é descrita e provada no monitoramento de um estudo de caso.

Abstract:
This dissertation is about the mapping and integration of the pure functional language Haskell to the Object Management Group's (OMG) Common Object Request Broker Architecture (CORBA). The purpose of this work is to create the definitions necessary for programs written in the Haskell language to successfully interoperate with programs written in any other programming languages operating within the OMG/CORBA environment. This work extended prior work in the areas of language integration into distributed environments, and language mappings to the OMG/CORBA environment. It also extended and synthesized the prior theoretical and applied research to integrate imperative and object-oriented characteristics into the Haskell programming language. In order to accomplish this objective, a language mapping from the OMG Interface Definition Language to Haskell was created. Specific extensions were created in Haskell to support the semantics of this interface definition language. These extensions also respected Haskell's pure functional, non-strict semantics as well. It is expected that the results of this work are sufficient so that object brokerage systems can be implemented to support the mapping and integration definitions defined in this dissertation. In addition, it is expected that the extensions and techniques defined in this work may have further utility in similar theoretical and applied problem domains.

Abstract: The present work proposes an alternative methodology for the development and evolution of AIOA, a software environment for the management and analysis of experimental data, being developed at Embrapa, Brazil. This new technique consists of the combined use of OMT (Object Modeling Technique) with the formal specification language SDL (Specification and Description Language), in its 1992 version SDL-92, presenting strong facilities on the software development process, allowing the validation, simulation and eventual code generation for software prototyping. From the system object model and after mapping to SOL-92, the formal specification is generated considering concepts such as reuse, inheritance, and system evolution. The validation, the simulation and code generation of the system is allowed through the use of the CASE tool SOT (SOL Oesign Tool - Telelogic, Sweden). The specification of the centralized AIOA to its evolution to distributed version are presented, validated and simulated. This is followed up with a specialization and validation of thedistributed AIOA, considering an arquitecture client-server with CORBA mechanism

Abstract:
The way in which application systems and software are built has changed dramatically over the past few years. This is mainly due to advances in hardware technology, programming languages, as well as the requirement to build better software application systems in less time. The importance of mondial (worldwide) communication between systems is also growing exponentially. People are using network-based applications daily, communicating not only locally, but also globally. The Internet, the global network, therefore plays a significant role in the development of new software. Distributed object computing is one of the computing paradigms that promise to solve the need to develop clienVserver application systems, communicating over heterogeneous environments. This study, of limited scope, concentrates on one crucial element without which distributed object computing cannot be implemented. This element is the communication software, also called middleware, which allows objects situated on different hardware platforms to communicate over a network. Two of the most important middleware standards for distributed object computing today are the Common Object Request Broker Architecture (CORBA) from the Object Management Group, and the Distributed Component Object Model (DCOM) from Microsoft Corporation. Each of these standards is implemented in commercially available products, allowing distributed objects to communicate over heterogeneous networks. In studying each of the middleware standards, a formal way of comparing CORBA and DCOM is presented, namely meta-modelling. For each of these two distributed object infrastructures (middleware), meta-models are constructed. Based on this uniform and unbiased approach, a comparison of the two distributed object infrastructures is then performed. The results are given as a set of tables in which the differences and similarities of each distributed object infrastructure are exhibited. By adopting this approach, errors caused by misunderstanding or misinterpretation are minimised. Consequently, an accurate and unbiased comparison between CORBA and DCOM is made possible, which constitutes the main aim of this dissertation.

Abstract:
Connecting heterogeneous databases through the World Wide Web (WWW) is crucial for most business organizations. The underlying complex problem is the handling of heterogeneity and communication between different data repositories (or database systems). Such interoperability is crucial as it enables the integration of business processes across different business organizations, and therefore becomes a key issue within the new generation of Web-based business applications (called Web Services). CORBA (Common Object Request Broker Architecture) provides protocols and components that allow interoperability between different software platforms (Tari & Bukhres, 2001), such as C++ and Java. However, CORBA does not deal with WWW-based interoperability. In this paper we propose an extension of one of the core elements of CORBA, called Portable Object Adapter (POA), to deal with persistency of business information. The proposed extension, called CODAR, manages the whole life cycle of persistent objects, including activation, deactivation, instantiation, and deletion. At the end of this paper we describe an extension of CODAR to deal with performance by including advanced caching and prefetching techniques.

Abstract:
With the interconnection of computers in networks, particularly through the Internet, it becomes possible to connect applications on distant computers. An application works perfectly whether it isdistant or local. Moreover, a distant applicationallows us to benefit from the following additional advantages: • Data and processes can be stored on a remote server that has a bigger storage capacity than the local host. Data can be shared between users using, for example, Remote Procedure Call (RPC), Remote Method Invocation (RMI), Java Message Service (JMS), and Enterprise JavaBeans (EJB) (Frénot, 2000): • Distant application can be used at the same time by several users; • Updating data and processes can be done only in one host; • Flexibility on distribution of the load: An application can be executed on the available machine; and • High availability: A faulty machine does not affect the others. Many approaches have been proposed and developed for communication between distant hosts on a network such as Message Passing (MP), Remote Evaluation (REV), Remote Object Invocation (ROI), Mobile Agents (MA), Common Object Request Broker Architecture (CORBA), Web Services (WS), RPC, and RMI (Dejan, LaForge, & Chauhan, 1998). In this article, we will focus on two particular paradigms: The Web Services and the Mobile Agents. WS defines a standard to invoke distant applications and to recover results across the Web. Its invocation is made in synchronous mode. MA has the faculty to move easily between a network’s hosts to execute user requests. MA communication is made in asynchronous mode. The fusion of these two complementary technologies will solve many problems. This article is composed of the following sections: In the first two sections, we introduce the concepts of WS and MA, their advantages and disadvantages. In the third section, we present different kinds of interaction between MA and WS. Finally, we study an example in the last section.

Abstract:
Cryptography has been used since ancient times in many different shapes and forms to protect messages from being intercepted. However, since 1976, cryptography started to be part of protected public communication when e-mail became commonly used by the public. Webmail (or Web-based e-mail) is an e-mail service intended to be primarily accessed via a web browser, as opposed to through an e-mail client, such as Microsoft Outlook, Mozilla‘s Thunderbird Mail. Very popular webmail providers include Gmail, Yahoo! Mail, Hotmail and AOL. Web based email has its advantages, especially for people who travel. Email can be collected by simply visiting a website, negating the need for an email client, or to logon from home. Wherever a public terminal with Internet access exists one can check, sends and receive email quickly and easily. Another advantage of web based email is that it provides an alternate address allowing user to reserve his/her ISP address for personal use. If someone would like to subscribe to a newsletter, enter a drawing, register at a website, participate in chats, or send feedback to a site, a web based email address is the perfect answer. It will keep non-personal mail on a server for you to check when you wish, rather than filling up your private email box. Web service is defined as “a software system designed to support interoperable machine-to-machine interaction over a network”. Web services are frequently just Internet application programming interfaces (API) that can be accessed over a network, such as the Internet, and executed on a remote system hosting the requested services. Other approaches with nearly the same functionality as web services are Object Management Group‘s (OMG) Common Object Request Broker Architecture (CORBA), Microsoft‘s Distributed Component Object Model (DCOM) or SUN‘s Java/Remote Method Invocation (RMI). Integrating Encryption with web service could be performing in many ways such as: XML Encryption and XML Signature. In this article we present client and Web-based E-mail, next generation E-mail and secure E-mail, followed by cryptography in web service and the last part is the future of web service security. The article start with the integration of cryptography with E-mail client and web base then the integration of cryptography and web service is presented. At the end of the major two sections: e-mail service and web service there is a general prospect vision of encryption future for e-mail service and web service. This section presents our view for the cryptography integration with the second generation of e-mail and web service.

Abstract:
Neste trabalho apresentamos uma abordagem de implementação do detector de falhas do FTCORBA (Fault Tolerant-Common Object Request Broker Architecture), utilizando a linguagem de programação Java integrada e o serviço COSNaming de uma implementação aberta do padrão CORBA. A abordagem utilizada neste trabalho para a implementação do detector de falhas propõe a monitoração periódica exclusivamente da réplica primária dos servidores. A monitoração das demais réplicas é executada apenas em caso de falha da réplica primária. Neste caso um novo servidor primário é eleito entre as réplicas sem falhas. Também é apresentado um exemplo de construção de uma aplicação tolerante a falhas utilizando o detector implementado.

Abstract:
Abstract In this paper, we discuss a distributed collaborative design for embodying concurrent engineering. The concept of a process-centric collaborative design is proposed to progress collaboratively an engineering design. It is implemented in the PEDWorks (Process-centric Engineering Design Workspace) as a prototype system for the Web-based collaborative workspace to integrate design activities in a distributed and heterogeneous computing environment. The PEDWorks has a client/server architecture, which consists of server applications such as a process controller, a design board, a communication server and a CAD server, and the client browsers with a Web-based process-driven user interface. We have conformed to CORBA (Common Object Request Broker Architecture) standard to support interoperability between distributed objects and have used JAVA to support cross-platform and distributed user access to PEDWorks on the Web. PEDWorks enables design teams to define the design process collaboratively, execute it in a distributed environment, share design information and communicate with each other.
