during the system designing we combine the result of system analysis with technology system structure and put forward a new software development model 在进行系统设计时,我们把系统分析的结果与所采用的技术体系结构相结合,提出了一种新的软件开发模式。
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 译文:螺旋模型是结合了设计和阶段与原型开发原理的一种软件开发模型,因此是一种从上至下和自下而上概念的良好的结合。
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 然后从快速、经济和高质量的实现大型软件系统的角度出发讨论了该系统的实现过程中所采用的基于构件的软件开发模型。
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 译文:瀑布模型的软件开发模式是在1970年首先被提出的,在发展中完善,通过线性阶段需求分析、设计、实施、测验(验证)、集成和维护。
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 然而从软件的发展历史来看,为了适应不同时期的软件需求和软件规模,软件的生产模式也从原始的软件作坊模式逐渐过渡到目前为软件行业所推崇的软件工厂模式。
