一 项目三层结构设计
在项目开发中,清晰明了的结构设计非常重要。它的重要性至少提现在三个方面:结构清晰;可维护性强;可扩展性高。
常用的项目结构设计中,三层架构设计非常实用。这种架构设计模式将整个程序分为三层:
用户视图层:用于与用户交互的,可以接受用户的输入,打印接口返回的数据。
逻辑接口层:接收视图层传递过来的参数,根据逻辑判断调用数据层加以处理并返回一个结果给用户视图层。
数据处理层:接受接口层传递过来的参数,做数据的增删改查。

一个项目如何从无到有
一 需求分析 1. 拿到项目,会先在客户那里一起讨论需求, 商量项目的功能是否能实现,周期与价格,得到一个需求文档。 2. 最后在公司内部需要开一次会议,最终得到一个开发文档, 交给不同岗位的程序员进行开发。 - Python: 后端,爬虫 - 不同的岗位: - UI界面设计: - 设计软件的布局,会分局软件的外观切成一张张图片。 - 前端: - 拿到UI交给他的图片,然后去搭建网页面。 - 设计一些页面中,哪些位置需要接收数据,需要进行数据交互。 - 后端: - 直接核心的业务逻辑,调度数据库进行数据的增删查改。 - 测试: - 会给代码进行全面测试,比如压力测试,界面测试(CF卡箱子)。 - 运维: - 部署项目。 二 程序的架构设计 1、程序设计的好处 1)思路清晰 2)不会出现写一半代码时推翻重写 3)方便自己或以后的同事更好维护 2、三层架构设计的好处 1)把每个功能都分层三部分,逻辑清晰 2)如果用户更换不同的用户界面或不同, 的数据储存机制都不会影响接口层的核心 逻辑代码,扩展性强。 3)可以在接口层,准确的记录日志与流水。 3、三层架构 一 用户视图层 用于与用户交互的,可以接受用户的输入,打印接口返回的数据。 二 逻辑接口层 接受 用户视图层 传递过来的参数,根据逻辑判断调用数据层加以处理, 并返回一个结果给 用户视图层。 三 数据处理层 接受接口层传递过来的参数,做数据的 - 保存数据 save() - 查看数据 select() - 更新数据 - 删除数据 三 分任务开发 四 测试 五 上线
