Component - based software development , cbsd 基于構(gòu)件的軟件開發(fā)
Cbsd ( component - based software development ) based on sa ( software architecture ) is a new method for system development 摘要基于軟件體系結(jié)構(gòu)的組件式軟件開發(fā)是一種新的系統(tǒng)開發(fā)方法。
Component - based software development ( cbsd ) is one of the most effective methods for the productivity and quality of the embedded software 在這種情況下,嵌入式軟件的質(zhì)量和開發(fā)效率往往會(huì)對(duì)一個(gè)嵌入式產(chǎn)品的成功起著決定性的影響。
The characteristics of com include : object . oriented , client / server , language independency , process transparency and reusablity . these characteristics make cbsd possible Com的特性有面向?qū)ο蟮奶匦裕蛻舳?服務(wù)器特性,語言無關(guān)性,對(duì)進(jìn)程的透明性和可復(fù)用機(jī)制。
Based on component - based software development ( cbsd ) , the effects of middleware in system architecture are analyzed , and then the promotion of component technology to middleware is illustrated 然后針對(duì)電子商務(wù)系統(tǒng),提出基于組件的電子商務(wù)中間件構(gòu)架,從構(gòu)架級(jí)實(shí)現(xiàn)系統(tǒng)的重用。
This paper also explains how to use the cbsd method in the course of system development . to show the system ' s adaptive ability to the changes and disturbances by reconfiguration , an example is given 作為系統(tǒng)應(yīng)用,本文通過實(shí)例說明了所開發(fā)的原型系統(tǒng)的運(yùn)行方法,驗(yàn)證了本系統(tǒng)通過兩方面重構(gòu)對(duì)車間各種變化的適應(yīng)能力。
The cbsd is adopted in the process of development of the system and it results in less developing time , less cost of development , more flexibility and maintainability and easy upgrade 在合作研究平臺(tái)的開發(fā)過程中,采用了基于構(gòu)件的軟件開發(fā)方法cbsd ,縮短了開發(fā)時(shí)間,降低了開發(fā)成本,同時(shí)也提高了整個(gè)系統(tǒng)的靈活性和可維護(hù)性,利于以后的系統(tǒng)升級(jí)。
With the development of component technology , the component - based software development ( cbsd ) has already been accepted widely . it becomes the effective way to tackle software crisis . component assembly technology is the key of cbsd 隨著構(gòu)件技術(shù)的日益成熟,基于構(gòu)件的軟件開發(fā)方法已被廣泛接受,逐步成為解決軟件危機(jī)、提高軟件生產(chǎn)率和確保軟件質(zhì)量的軟件開發(fā)范例。
Under such circumstance , software component technology is thriving these years , and there are many technologies available , including com / dcom , corba and javabeans / ejb . component - based software development ( cbsd ) is receiving considerable attention within the last years 近年來,面向?qū)ο蟮臉?gòu)件化軟件技術(shù)蓬勃發(fā)展,國(guó)際上出現(xiàn)了像corba , com ole , javabeans ejb等構(gòu)件的標(biāo)準(zhǔn)和技術(shù),基于構(gòu)件的軟件開發(fā)( cbsd )日益受到重視。
