Because in the 8 kinds of web frameworks which are used by Golang, the Echo and Gin both have the advantages: faster and more less memory using which defeat all the other web frameworks, but the menbers in the developers have experience at useing Echo, so use it.
因为在主流的8种Go语言的web框架中，Echo和Gin都有着别的框架无法媲美的有点：速度快 & 0内存占用，而项目编写人员中有使用Echo框架的经验，所以最后选择了使用Echo框架作为本项目的后端web框架。
From the begining, we consider the Beego framework because this is created by Chinese and wrote by all the Golang, in addition, there are lots of examples and original documents in real Chinese language. But we find that the Beego is the Golang's PHP MVC -- it didn't fully use the advantages of Golang.
原来也有考虑过Beego框架，因为Beego框架是国人开发，并保持100%Go语言编写的『准优良血统』，拥有原生的中文文档和大量的学习例子。但是经过考察，发现Beego框架也只是将PHP语言上那一套MVC思想使用Go语言复现了一遍，并且并没有使用Go语言对比其他语言的优势。所以使用这就是为什么不实用Beego，并且评价它为『准优良血统』的原因。
On the other hand, we choose the MySQL as system's database, because the compatibility of MySQL is the strongest on the internet.
在数据库的选择上，我们选择了开源并且使用面广泛的MySQL关系式数据库，因为就互联网上主流的数据库操作来说，对MySQL数据库的操作的兼容性是最高的，所以选择了MySQL。
And we also think about the Redis, bucause the "fastest database on the earth" is really attractive for us. Unfortunetly, it just the key-value structure database, but the table and relative database is our indeed need. So...
原先Redis也是备选之一，因为Radis拥有『世界上最快数据库』的美誉，但是因为它是单线程，并且数据存取关系是『键值对』，对表形数据有些不友好。所以遂放弃之。
The system was in 3 layers and 2 modules combination: main entrance, router, sql controller.
总共分为两个模块三层结构，分别为main(入口)，router(路由)，sql(数据库控制器)。
the entrance use the Echo framework to access the http request and call the Echo router thread to handle the business. In the business function, codes would call the the sql controller to modify the database.
入口控制简易HTTP服务，以及整个后端的配置参数设置。入口接到的http操作请求之后，会调用路由模块新开线程进行业务处理。在业务实现代码中会调用相应的数据库控制模块，对数据库做出相应的修改。
