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 分布式對象技術始于90年代初,已經(jīng)發(fā)展成為當今分布異構環(huán)境下,建立應用系統(tǒng)集成框架和標準構件的核心技術。
Then three core technologies , which are distributing object technology , modern computing model and network protocol technology and intelligent collaboration technology are focused 并對支撐技術中三大核心成分? ?分布式對象技術、新型計算模式及網(wǎng)絡協(xié)議、智能合作技術進行了深入的研究。
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 本文介紹了分布式對象技術和多層體系結構的發(fā)展、特點,詳細討論了幾種典型的組件技術的原理及實現(xiàn)。
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 而分布式對象技術提供組件的服務,正好具有這些優(yōu)點,因而基于分布式對象技術的數(shù)據(jù)采集系統(tǒng)研究和設計成為可能和必要。
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章主要介紹了計算模式的演變。討論分析了集中計算模式、分布式計算模式,最后介紹了分布式對象技術和中間件的相關技術。
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規(guī)范的分布式對象技術來構造軟構件集成框架,然后將agent技術引入到分布式構件管理中。
The application based on internet is a distributed system , whose development must deal with some problems , such as security , reliability , etc . distributed object technology is the key to solve the above problems 鑒于基于internet的應用是一種分布式應用系統(tǒng),需要解決安全、可靠性等方面的問題,分布式對象技術成為解決這些問題的方法。
Moreover , rmi of java expresses the idea of distributed object technology , and inherits every virtue of java . therefore , it is the best choice of developing large distributed system 而java遠程方法調用( rmi : remotemethodinvocation )很好地體現(xiàn)了分布式對象技術的思想,并且充分繼承了java計算平臺的各種優(yōu)點,是開發(fā)大型分布式應用的理想選擇。
With the development of component - based software , components begin to be used in gis domain . now , the maturity of distributed object technology lets component become an important tool in weggis construction 隨著構件技術在軟件開發(fā)中的廣泛使用,地理信息系統(tǒng)也走上了構件化的發(fā)展道路,分布式對象技術的成熟更使得構件技術成為開發(fā)webgis的得力工具。
In the technological perspective , scm application integration is based on enterprise application integration ( ea1 ) and the main technology related is distributed object technology , xml and web service 在技術方面,供應鏈管理應用集成的基礎是企業(yè)應用集成。企業(yè)應用集成可分為深度集成和廣度集成,涉及的關鍵技術包括分布式對象技術, xml和webservice 。
