during the system designing we combine the result of system analysis with technology system structure and put forward a new software development model 在進行系統(tǒng)設計時,我們把系統(tǒng)分析的結果與所采用的技術體系結構相結合,提出了一種新的軟件開發(fā)模式。
the spiral model is a software development model combining elements of both design and prototyping-in-stages, so it's a healthy mix of top-down and bottom-up concepts 譯文:螺旋模型是結合了設計和階段與原型開發(fā)原理的一種軟件開發(fā)模型,因此是一種從上至下和自下而上概念的良好的結合。
then from the view of fast, economically and highly grade realizing a large-scale software system, the article discussed the software development model based on the component technology as used in realizing this system 然后從快速、經(jīng)濟和高質(zhì)量的實現(xiàn)大型軟件系統(tǒng)的角度出發(fā)討論了該系統(tǒng)的實現(xiàn)過程中所采用的基于構件的軟件開發(fā)模型。
the waterfall model is a software development model first proposed in 1970, in which development proceeds linearly through the phases of requirements analysis, design, implementation, testing ( validation ), integration and maintenance 譯文:瀑布模型的軟件開發(fā)模式是在1970年首先被提出的,在發(fā)展中完善,通過線性階段需求分析、設計、實施、測驗(驗證)、集成和維護。
while from software development historical point of view, we can find out, in different period, by adapting to different software requirements, the software development model is also changed, from the original software workshop mode moving to the canonized software factory model 然而從軟件的發(fā)展歷史來看,為了適應不同時期的軟件需求和軟件規(guī)模,軟件的生產(chǎn)模式也從原始的軟件作坊模式逐漸過渡到目前為軟件行業(yè)所推崇的軟件工廠模式。
