Therefore , n - layered architecture based on b / s structure , distributed object technology and groupware technology are born , which support for developing expansible easy - maintainable and high - powered large application software system not only in theory but also in practice 它們?cè)诶碚摵图夹g(shù)上為開發(fā)可擴(kuò)展,易維護(hù),高性能的大型應(yīng)用軟件系統(tǒng)提供了很好的支持。
The main works in this thesis are done as follow : 1 . through research on the current optimum design subject and the distributed object technology in computer domain , the distributed computation has been brought into the optimum design subject 課題所做的主要工作如下: 1 .通過對(duì)當(dāng)前優(yōu)化設(shè)計(jì)學(xué)科和計(jì)算機(jī)領(lǐng)域的分布式對(duì)象技術(shù)的研究,把分布式計(jì)算引入到優(yōu)化設(shè)計(jì)學(xué)科。
Corba is a new distributed object technology with the characteristics of having nothing to do with the languages and operation system . the combination of corba and java can be mutually complemented Corba作為一種新的分布式對(duì)象技術(shù),具有與開發(fā)語(yǔ)言、與操作系統(tǒng)無(wú)關(guān)以及集成性的特點(diǎn),它與java的集成可以使二者優(yōu)勢(shì)互補(bǔ),在它們的結(jié)合上corba處理網(wǎng)絡(luò)的透明性, java處理實(shí)現(xiàn)的透明性。
In this paper , theories about data transfer technique in distributed system are discussed . first , distributed object technology and the common object request broker architecture are analyzed because they are the bases of my research work 本文基于corba (通用對(duì)象請(qǐng)求代理結(jié)構(gòu))技術(shù)提出一種在分布節(jié)點(diǎn)間提供數(shù)據(jù)傳輸服務(wù)的數(shù)據(jù)服務(wù)模型,并給出數(shù)據(jù)服務(wù)在分布式監(jiān)控系統(tǒng)中的一種實(shí)現(xiàn)。
The workflow infrastructure is established using distributed object technology to support the architecture in the cooperation environment of had ( heterogeneous , autonomous , distributed ) . workflow modeling is the first step to implement the workflow management 運(yùn)用分布式對(duì)象技術(shù)建立了工作流管理系統(tǒng)基礎(chǔ)結(jié)構(gòu),為多個(gè)用戶在分布、自治、異構(gòu)的協(xié)同環(huán)境中進(jìn)行產(chǎn)品及其相關(guān)過程設(shè)計(jì)提供了有力的支持。
In the development of flood control information system ( fcis ) , we try to make the best use of software components and application framework to promote the system quality and efficiency , and use distributed object technology to advance system integration 針對(duì)這種情況,本文的基本思路是:在防汛信息系統(tǒng)開發(fā)過程中,充分利用軟件構(gòu)件和應(yīng)用框架來(lái)提高系統(tǒng)質(zhì)量和效率,利用分布式對(duì)象技術(shù)來(lái)解決系統(tǒng)集成問題。
In section two , i manage to introduce the three main distributed object technologies , including dcom of microsoft inc , ejb of sun inc and corba of omg in details . and manage to analysis the difference between them 在第一部分介紹的基礎(chǔ)上,第二部分闡述了用于企業(yè)分布式系統(tǒng)構(gòu)建的三種基于組件的分布式對(duì)象技術(shù): microsoft公司的dna dcom 、 sun公司的j2ee ejb以及omg集團(tuán)的corba ,分析了各種技術(shù)的優(yōu)缺點(diǎn)及適應(yīng)的場(chǎng)合。
The distributed object technology has become a kernel one setting the service application frame a nd software component and shown a powerful life force in the development of large - scale distributed application system . there are three typical mainstream technologies 分布式對(duì)象技術(shù)已經(jīng)成為建立服務(wù)應(yīng)用框架和軟件構(gòu)件的核心技術(shù),在開發(fā)大型分布式應(yīng)用系統(tǒng)中表現(xiàn)出強(qiáng)大的生命力,并逐漸形成了三種具有代表性的主流技術(shù)。
The component which is implemented with distributed object technology , not only can be reused and increase the efficiency , but also save the resources of hardware and reduce the cost of maintenance by replacing the problematic module at any moment 分布式對(duì)象技術(shù)追求的目標(biāo)是軟件無(wú)縫連接,即插即用。利用分布式對(duì)象技術(shù)實(shí)現(xiàn)的組件不僅可重復(fù)使用和提高效率,還可以節(jié)省硬件資源,隨時(shí)更換有問題的模塊,以降低其維護(hù)成本。
