公共对象请求代理结构（CORBA）是对象管理组织（OMG──Object Management Group）对分布对象计算的框架、结构和接口进行标准化后提出的一种规范，《联系人；欧先生》

《QQ邮箱：2479261344@qq.com》为基于对象的分布计算系统的移植和互操作提供了有力的保证【5】，可以说CORBA是传统的分布式处理技术与面向对象技术相结合的产物。OMG为了解决分布计算系统的异构性提出了对象管理框架结构(OMA──Object Management Architecture)，如图1所示。其核心是提供一条软件总线来规范和容纳不同对象之间的通信与协作，这条总线就是对象请求代理(ORB──Object Request Broker)。目前已有许多支持CORBA标准的产品出现。
图1 对象管理框架结构
CORBA的核心部件是接口定义语言（IDL──Interface Definition Language），它对于对象的作用就象数据描述语言DDL对于数据库的作用一样，人们可以使用它定义对象的接口，其他对象通过该接口与该对象进行交互。IDL的一个重要特点是其语言的独立性，即它是一种描述型语言，而不是一种程序编写语言，这样使得对象接口的定义与对象的实现分开，允许对象用不同的程序设计语言实现但仍能保持其相互之间的通信畅通。目前，ODL到C、C++、Smalltalk、Ada95、JAVA等已经有了映象规范。
