信息系统—系统开发路线、方法与工具

系统的开发路线包括：模型驱动开发路线、快速应用开发路线、商用软件开发路线、混合开发路线。模型驱动开发路线分为：面对过程开发、面向数据开发、面向对象开发。快速应用开发路线包含：迭代式开发、敏捷式开发；商用软件开发路线包含：购买现有软件、现场软件二次开发；混合开发路线：各种路线混合。

the development route of the system includes: model-drivendevelopment route, rapid application development route, commercialsoftware development route, and hybrid development route.model-driven development routes are divided into: process-orienteddevelopment, data-oriented development, and object-orienteddevelopment. the rapid application development route includes:iterative development and agile development; the commercialsoftware development route includes: purchase of existing software,on-site software secondary development; hybrid development route:various routes are mixed.

结构化的基本思想

structured basic ideas

1、将软件生命周期划分为若干明确定义的阶段。2、预定好各阶段任务，并实施阶段性评审。3、按准则、按部就班地进行开发.4、以文档形式驱动的，上一阶段的结果作为本阶段的输入。

1. divide the software life cycle into several clearly definedstages. 2. predetermine tasks at each stage and implement periodicreviews. 3. develop according to the guidelines and step by step.4. driven in the form of documents, the results of the previousstage are used as the input of this stage.
