Distributed object technology had been put forward in 1990 . it has had rapid development to become the core one in buiding system integration frames and standard components 分布式对象技术始于90年代初，已经发展成为当今分布异构环境下，建立应用系统集成框架和标准构件的核心技术。
Then three core technologies , which are distributing object technology , modern computing model and network protocol technology and intelligent collaboration technology are focused 并对支撑技术中三大核心成分? ?分布式对象技术、新型计算模式及网络协议、智能合作技术进行了深入的研究。
As a worldwide industry standard for constructing distributed object software system , corba provide service named corba security to promise safety ^ stable communication between distributed objects Corba技术作为分布式对象技术的业界标准，为了确保对象通信的安全性，提供有corba安全服务。
This paper introduces the progresses and characters of distributed object technology and multilayer framework , and discusses the principles and realizations of several typical component technologies 本文介绍了分布式对象技术和多层体系结构的发展、特点，详细讨论了几种典型的组件技术的原理及实现。
Several mainstream technology on distributed object was analyzed in the software development process . a server model integrating corba and ejb norm was adopted in the development 在开发过程中，分析了现阶段几种流行的分布式对象技术，取众家之所长，采用集成corba和ejb技术标准的服务器开发模型进行开发。
Distributed object technology presents component service and is rightly provided with these virtues , which makes the research and design of data acquisition system based on it possible and necessary 而分布式对象技术提供组件的服务，正好具有这些优点，因而基于分布式对象技术的数据采集系统研究和设计成为可能和必要。
With the development of technology of distributed objects and the requirement of large distributed applications , object persistence makes an important role in the development and running of applications 随着分布式对象技术的发展和大型应用程序的需求，对象的持久化问题在应用程序的开发与运行效率方面扮演着非常重要的角色。
The second chapter details the history of distributed computing , analysises collected computing model and distributed computing model and at last introduces middleware and distributed object technology 第2章主要介绍了计算模式的演变。讨论分析了集中计算模式、分布式计算模式，最后介绍了分布式对象技术和中间件的相关技术。
Information characteristics of distributed manufacturing system , and supporting technologies for distributed manufacturing system are discussed , which include computing mode , component reuse , and distributed object 阐述了分布式制造系统的信息特点和基于构件的分布式制造信息集成的支撑技术? ?计算模式、构件复用和分布式对象技术。
Secondly , it adopts the distributed object technology according with corba criteria to construct the integrated framework of software component , and then introduces agent technology to the management of distributed components ( 2 )采用符合corba规范的分布式对象技术来构造软构件集成框架，然后将agent技术引入到分布式构件管理中。
