架构设计
三层架构
视图层
视图层是应用程序的用户界面和通信层，供最终用户与应用程序进行交互。 其主要目的是向用户显示信息并从用户收集信息。 此顶级层可以在（例如）Web 浏览器上运行、作为桌面应用程序运行或作为图形用户界面 (GUI) 运行。 Web 表示层通常使用 HTML、CSS 和 JavaScript 开发。 可根据平台以各种不同语言编写桌面应用程序。
接口层
接口层，也称为逻辑层或中间层，是应用程序的核心。 在该层中，将采用业务逻辑（一组特定的业务规则）处理从表示层收集到的信息， 有时也会处理数据层中的其他信息 。 接口层还可以添加、删除或修改数据层中的数据。
接口层通常使用 Python、Java、Perl、PHP 或 Ruby 开发，并使用 API 调用与数据层通信。
数据处理层
数据处理层层（有时称为数据库层、数据访问层或后端）可供存储和管理应用程序所处理的信息。 这可以是关系 数据库管理系统，例如 PostgreSQL、MySQL、MariaDB、Oracle、DB2、Informix 或 Microsoft SQL Server，也可以是 NoSQL 数据库服务器，如 Cassandra、CouchDB 或 MongoDB。
在三层应用程序中，所有通信均通过接口层进行。 视图层和数据层无法直接彼此通信
