    Corba: Common Object Request Broker Architecture

    Uploaded by

    Puspala Manojkumar
    CORBA (Common Object Request Broker Architecture) is a standard that allows software components written in multiple computer languages and running on multiple computers to communicate. It provides an object-oriented approach to RPC (Remote Procedure Call) with additional services such as object registration and lookup. The key components of CORBA include the Object Request Broker (ORB), Object Services, Common Facilities, and Application Objects.

    CORBA

    Common Object Request


    Broker Architecture
    CORBA
    What is it? [1]
    „ Object Request Broker
    …A common communication bus for
    transparently message passing between
    objects
    „ Object Services
    …a collection of services (interfaces and objects)
    that support basic functions for using and
    implementing objects.
    CORBA
    What is it? [2]
    „ Common Facilities
    …a collection of services that many applications
    may share, but which are not as fundamental
    as the Object Services.
    „ Application Objects
    … products of a single vendor on in-house
    development group that controls their
    interfaces.
    CORBA
    History – 1.0 (Oct. 1991~Dec.1993)
    „ CORBA Object model ( Core 92 )
    „ Interface Definition Language (IDL)
    „ Mapping from IDL to the C language.
    „ the core set of APIs for dynamic request
    management and invocation and Interface
    Repository.
    „ interfaces for the Basic Object Adapter and
    memory management
    CORBA
    History – 2.0~2.3 (Aug.96~ Jun.99 )
    „ General Inter-ORB Protocol / Internet
    Inter-ORB Protocol (GIOP/IIOP )
    „ Portable Object Adapter (POA)
    „ Collaboration with OLE2/COM
    „ Mapping from IDL to Java, Cobol, Ada,
    Smalltalk, C++
    CORBA
    History – 2.4~3.0 (Feb. 2001~ ?? )
    „ Java and Internet Integration
    … Objects Passable by Value
    … Java-to-IDL Mapping
    … Interoperable Name Service
    „ Asynchronous Messaging and Quality of Service
    Control
    „ Minimum, Fault-Tolerant, and Real-Time
    CORBA
    „ CORBAcomponents and CORBAscripting
    CORBA
    CORBA versus RPC
    „ RPC: When a specific function is called, the data
    type of parameters are fixed
    „ CORBA: The polymorphism of object is more
    flexiable.
    „ RPC: Language dependent
    „ CORBA: Language independent
    „ RPC: Get operation only
    „ CORBA: Support push operation
    CORBA
    Advantages
    „ Static and dynamic method invocations
    „ High-level language bindings
    „ Self-describing system
    „ Location transparency
    „ Built-in security and transactions
    „ Coexistence with existing systems
    CORBA Application
    Object Web Server
