数据库你自己弄吧，我没时间弄了！初学得多动手哦
编程技术
开发小程序需要的是编程基础，需要学习的技术如下：
1、微信小程序wxml，这个语言的编程理念和html网页的编程技术是类似的。
2、微信小程序之wxss，就是微信的css。微信把网页编程里运用的css，换成了自己的开发语言，wxss，其实主要的实现思想理念也和网页的开发技术基本没什么不同，也是一些标签的简单替换，大部分和原先的css、基本不误。
3、微信小程序之js，如果你想开发一款微信小程序学会微信小程序的js是必须要精通的
4、微信小程序之json，简单来说json就是微信小程序的一门主次的界面，工程师们可以通过json控制上下菜单栏、主次的页面展示顺序，不过用的频率不高，只是在基本的小程序的框架构架才会应用到。
其实，小程序类似于H5面，提供了视图层描述语言，需要掌握WXML和WXSS以及基于JavaScript的逻辑层框架，这里wxml相当于html，wxss相当于css。
