Django
- a back-end server side web framework.
- free, open source and written in Python.
Django follows the MVT design pattern (Model View Template):
- Model The model provides data from the database.
  - The models are usually located in a file called models.py.
- View: A request handler that returns the relevant template and content - based on the request from the user.
- Template: A text file (like an HTML file) containing the layout of the web page, with logic on how to display the data.
project
- A Python package – i.e. a directory of code – that contains all the settings for an instance of Django.
- This would include database configuration, Django-specific options and application-specific settings.
app
- A Django Application is created to perform a particular functionality for your entire web application.
- can then be plugged into other Django Projects
Project 与 app 之间的关系：
- 一个 Project 可以包含多个 app；
- 在 Project 中的每个 app 实现一个独立功能；
- 一个 app 可以在多个 Project 中；
- 一个 app 仅仅是遵循 Django 约定的Python 包。
django-admin 工具是 Django 管理命令行工具之一，安装好 Django 包后可以直接调用。
