TINA components used for service dubscription and deployment

This paper presents a TINA-based services platform for deploying and provisioning of services, especially services supporting dynamic communication processes between individuals, such as required for distributed teamwork. The paper gives an overview of the platform architecture, and discusses two topics in more detail: (1) the Distributed Software Component (DSC) framework, which considerably facilitates the development of components from which the platform is built, and (2) some specific components of the platform, which play a crucial role in service management and deployment. In addition, a brief\ud evaluation of CORBA (Common Object Request Broker Architecture) ORBs (Object Request Broker) is given, based on the experience of using CORBA as the underlying distributed processing environment for the platform

Application of Common Object Request Broker Architecture (CORBA) in biomedicine

Биологичните разработки днес зависят от широк диапазон от софтуер, взаимодействащ си с голям брой различни източници на данни. Съществуват няколкостотин важни източника, които се различават както по големина, така и по сфера на действие. Многобройни групи от учени разработват и публикуват тези биологични данни в най-различни формати. През последните години стана ясно, че е от съществено значение да бъде открит начин, по който различните софтуери, хардуери и източници на данни да работят гладко помежду си, или казано по друг начин как да бъде постигната интероперативност. Направени бяха много опити да се осигури стандартен формат данни, но никой от тях не бе широко възприет. Oбщата архитуктура за посредници при запитвания за обекти (CORBA) дефинира набор от стандарти, който образува свързана рамка, в която независимите източници на данни и техните услуги могат да бъдат достигнати. В тези стандарти влизат формалният език, езика за интерфейсна дефиниция (IDL), в който са специфицирани данните и услугите и ORB – посредник при запитвания за обекти, който е необходим, за да се реализират тези услуги. Темата на настоящата дипломна работа е разработване на сайт, запознаващ читателите и потребителите с приложението на Общата архитектура за посредници при запитвания за обекти Common Object Request Broker Architecture (CORBA) в биомедицинската информатика. Работата има за цел да се направи обзор и практическо описание на използването на CORBA във важни задачи от биоинформатиката, както и да осигури добро разбиране на основните механизми на архитектурата, да даде общ поглед на нейните компоненти и да запознае читателите и потребителите с терминологията, използвана в OMG документацията.“Приложение на Common Object Request Broker Architecture (CORBA) в биомедицината” дипломант: Аглика Петрова Иванова научен ръководител: доц.

Component technologies: Java Beans, COM, CORBA, RMI, EJB and the CORBA component model

This one-day tutorial is aimed at software engineering practitioners and researchers, who are familiar with objectoriented analysis, design and programming and want to obtain an overview of the technologies that are enabling component-based development. We introduce the idea of component-based development by defining the concept and providing its economic rationale. We describe how object-oriented programming evolved into local component models, such as Java Beans and distributed object technologies, such as the Common Object Request Broker Architecture (CORBA), Java Remote Method Invocation (RMI) and the Component Object Model (COM). We then address how these technologies matured into distributed component models, in partiuclar Enterprise Java Beans (EJB) and the CORBA Component Model (CCM). We give an assessment of the maturity of each of these technologies and sketch how they are used to build distributed architectures

An approach to building a secure and persistent distributed object management system

The Common Object Request Broker Architecture (CORBA) proposed by the Object Management Group (OMG) is a widely accepted standard to provide a system level framework in design and implementation of distributed objects. The core of the Object Management Architecture (OMA) is an Object Request Broker (ORB), which provides transparency of object location, activation, and communications. However, the specification provided by the OMG is not sufficient. For instance, there are no security specifications when handling object requests through the ORBs. The lack of such a security service prevents the use of CORBA from handling sensitive data such as personal and corporate financial information; In view of the above, this thesis identifies, explores, and provides an approach to handling secure objects in a distributed environment along with a persistent object service using the CORBA specification. The research specifically involves the design and implementation of a secured distributed object service. This object service requires a persistent service and object storage for storing and retrieving security specific information. To provide a secure distributed object environment, a secure object service using the specifications provided by the OMG has been designed and implemented. In addition, to preserve the persistence of secure information, an object service has been implemented to provide a persistent data store; The secure object service can provide a framework for handling distributed object in applications requiring security clearance such as distributed banking, online stock tradings, internet shopping, geographic and medical information systems

Integration, management and communication of heterogeneous design resources with WWW technologies

Recently, advanced information technologies have opened new pos-sibilities for collaborative designs. In this paper, a Web-based collaborative de-sign environment is proposed, where heterogeneous design applications can be integrated with a common interface, managed dynamically for publishing and searching, and communicated with each other for integrated multi-objective de-sign. The CORBA (Common Object Request Broker Architecture) is employed as an implementation tool to enable integration and communication of design application programs; and the XML (eXtensible Markup Language) is used as a common data descriptive language for data exchange between heterogeneous applications and for resource description and recording. This paper also intro-duces the implementation of the system and the encapsulating issues of existing legacy applications. At last, an example of gear design based on the system is il-lustrated to identify the methods and procedure developed by this research
