一些关于存储web/APP的重设计

这是一款用于后端的存储产品，是学生阶段实习时候的项目，由于信息的保密，故将部分地方进行了重设计。也算了是自己的练习，不作商用。若有什么不足，欢迎大家指教，谢谢！

This is a storage product for the back-end. It was my internship project when I was a student. Due to the confidentiality of the information, some parts were redesigned. Also calculate is own exercise, do not make commercial. If there are any shortcomings, welcome to advise, thank you！
