摘 要

如今基于構(gòu)件的軟件復(fù)用和開發(fā)被認(rèn)為是提高軟件生產(chǎn)率和軟件質(zhì)量的有效途徑。一般來說，基于構(gòu)件的軟件復(fù)用包括三個相關(guān)的過程：構(gòu)件的開發(fā)，構(gòu)件的管理和基于構(gòu)件組裝的系統(tǒng)開發(fā)。在基于構(gòu)件的軟件開發(fā)中，系統(tǒng)開發(fā)的重點從系統(tǒng)設(shè)計變成構(gòu)件組裝。本文研究的就是這種基于構(gòu)件的軟件自動組裝技術(shù)。
開發(fā)該系統(tǒng)，我使用面向?qū)ο蟮目梢暬_發(fā)工具Visual Basic 6.0，運用計算機軟件技術(shù)和面向?qū)ο蟮能浖_發(fā)方法。首先制作出用于模擬構(gòu)件的芯片（芯片的部分內(nèi)部功能由指導(dǎo)老師提供），其次設(shè)計出一個相對比較簡單的連接件（因連接件的開發(fā)另有同學(xué)研究），最后采用事件觸發(fā)的方法，運用連接件實現(xiàn)模擬構(gòu)件（芯片）間的組裝，同時，實現(xiàn)功能芯片間的模擬防真。
通過該系統(tǒng)的研究開發(fā)，使我獲益匪淺，不但對基于構(gòu)件的軟件自動組裝技術(shù)有了更深刻的認(rèn)識，而且對開發(fā)工具Visual Basic 6.0有了更全面的掌握。當(dāng)然，限于作者水平，本系統(tǒng)難免有疏漏和不完善之處，敬請各位老師不吝指正。

Abstract

Now component-based software reuse and development is considered as an effective and efficient approach to improve the productivity and quality of software development. Generally, component-based software reuse includes three processes: component development, component management and system development which is based on component composition. In the component-based software development, the emphasis of system development has been turned to component composition from system design. This text is studying the technology of component-based software composition automatically.
In order to develop this system, I used the objected-oriented visual tool Visual Basic 6.0 , computer software technology and the method of objected-oriented software development .Firstly, I developed the chips whose some interior functions were offered by the teacher to simulate components. Secondly, I developed a simple connective-ware , because there was another student studied it specially. Finally, I let the system come true with the method of event-driven and connective-ware, simultaneity, these chips could simulate the truth.
By developing this system, I benefit a lot, not only understand the technology which component-based software composition automatically even more, but also master the tool Visual Basic 6.0 to develop software even more comprehensive. Certainly, limited to the author, this system was hard to avoid oversights and faultiness, please every teacher point out unstinted.

Keywords：component; software component; connective-ware; software reuse; component composition
