This paper analyzes two software development processes , which are xp and rup . based on the above analysis , a new software development process is brought forward , which is a speed development process on the basis of distributed object technology , for short speed development process 文章在對當(dāng)前存在的兩種軟件開發(fā)過程( xp和rup )進(jìn)行分析和比較的基礎(chǔ)上提出了一種基于分布式對象技術(shù)的快速開發(fā)過程(以下稱為快速開發(fā)過程) 。
Owing to the dynamics , uncertainty and many limitations of mobile network environment , traditional distributed object technology ( dot ) , which plays an important role in many network applications , becomes awkward and even inapplicable in mobile scenarios 分布對象技術(shù)對于各種網(wǎng)絡(luò)應(yīng)用有非常重要的作用,但由于移動(dòng)網(wǎng)絡(luò)環(huán)境和應(yīng)用存在相當(dāng)程度的動(dòng)態(tài)性、不確定性和多種限制條件,傳統(tǒng)技術(shù)在移動(dòng)環(huán)境中顯得不夠靈活、甚至不適用。
Of them , distributed object technology makes every object in application system remain anywhere in the net by the shape of isolated physical entity and be visited remotely by other objects . distributed object technology also supports for the reality of groupware ' s second use 其中分布式對象技術(shù)使得軟件系統(tǒng)的各個(gè)對象能以獨(dú)立的物理實(shí)體的形式駐留于網(wǎng)絡(luò)中的任何地方,并且可被其它對象遠(yuǎn)程訪問,為組件復(fù)用的實(shí)現(xiàn)提供了強(qiáng)有力的支持。
This paper firstly introduced the origin and development of the two kinds of distributed object technology ? corba and com , after that , it discussed their theory fundament , adaptive domain and prospective . distributed object technology aims at seamless interoperation between software , plug and play 本文首先分別就目前兩大分布式對象技術(shù)corba和com的由來和發(fā)展作了簡明扼要的介紹,同時(shí)對它們的理論基礎(chǔ)、應(yīng)用領(lǐng)域和發(fā)展前景進(jìn)行了討論。
Currently the integrated framework research mainly focuses on the distributed object technology based on software component and software bus . however , the technology of software component and software bus lack for the efficient means to depict the configuration and mutual association of components 目前集成框架的研究主要建立在基于軟構(gòu)件軟總線方式的分布對象技術(shù)上,然而軟構(gòu)件軟總線的研究并未提供有效手段去透明地描述軟構(gòu)件的配置和相互關(guān)聯(lián)。
However , xml is still in developing and present middle - ware technology can " t successfully separate content and display , which makes xml - based systems difficult to implement and manage , hard to show advantages of xml . distributed object technology stemmed in 1990 " s 但現(xiàn)在xml仍在發(fā)展之中,現(xiàn)有的中間件技術(shù)還不能實(shí)現(xiàn)內(nèi)容、邏輯與形式的完全分離,使得基于xml的web應(yīng)用系統(tǒng)開發(fā)仍存在實(shí)現(xiàn)困難、管理復(fù)雜的問題,很多應(yīng)用并不能充分體現(xiàn)出xml的優(yōu)越性。
The main content of this paper is described as follows : firstly , introduces distributed object technologies and windows dna respectively , mostly analyses their architectures and points out their features and advantages , then discusses component object model and researches the key component in windows dna - - com and com + 本文的主要內(nèi)容包括如下:首先,對分布式對象技術(shù)和windowsdna體系結(jié)構(gòu)做了介紹,分別對它們的結(jié)構(gòu)進(jìn)行了分析,指出了它們的特點(diǎn)和優(yōu)勢。
In this paper , under the application background of oil company requirement , through to analyze and study the character of distributed object technology and software reused technology and the component technology , we build a oilmis application framework based on corba . then we bat around the design and development of the application framework , and provide one kind of methods for developing software systems by component . in succession , we analyze the character of the application framework and show it can be a valid project for oil field 本文以油庫信息管理系統(tǒng)為應(yīng)用背景,通過對分布式對象技術(shù)、軟件復(fù)用技術(shù)、構(gòu)件技術(shù)的分析和研究,結(jié)合油庫信息管理系統(tǒng)的應(yīng)用特點(diǎn),建立了一個(gè)基于corba構(gòu)件服務(wù)器的oilmis應(yīng)用程序框架;接著從框架的設(shè)計(jì)、開發(fā)等方面進(jìn)行了詳細(xì)的討論,給出了基于構(gòu)件的框架的一般設(shè)計(jì)開發(fā)方法;然后從體系結(jié)構(gòu)的角度對oilmis框架模型進(jìn)行了分析,討論了基于此框架模型的系統(tǒng)開發(fā)方法,說明此種框架結(jié)構(gòu)能夠作為油庫信息領(lǐng)域的一個(gè)有效解決方案;最后通過儲罐自動(dòng)計(jì)量子系統(tǒng)中一個(gè)業(yè)務(wù)構(gòu)件實(shí)現(xiàn)的實(shí)例,演示了oilmis中構(gòu)件的實(shí)現(xiàn)方法。
