软件生命周期瀑布模型_软件生命周期模型：瀑布模型

软件生命周期瀑布模型

Hello guys, so today we would be looking at one of the widely known and the simplest softwarelife cycle model i.e. waterfall models, as the name suggests the reason for naming this model as awaterfall modelis that the sequence of steps that are followed in this model resemble the flow of awaterfall. As the water falls from top to down, inwaterfall modelyou are allowed to move in the direction as that of a waterfall therefore backtracking is not possible in this type of model.

大家好，所以今天我们将看一个广为人知且最简单的软件生命周期模型，即瀑布模型，顾名思义，将该模型命名为瀑布模型的原因是：这个模型很像瀑布的流动。 当水从上到下下落时，在瀑布模型中，您可以沿瀑布的方向移动，因此在这种类型的模型中无法进行回溯。

The sequence of steps that are followed in this model are as follows:

此模型中遵循的步骤顺序如下：

Requirement gathering

需求收集

Designing of the model

模型设计

Implementation along with unit testing

与单元测试一起实施

Integration and system testing

集成和系统测试

Operation and maintenance process

运维流程

Flowchart representation of the following sequence of steps is given below:
