问题描述

I want to create a system that can upload file(.txt, .doc, .pdf and so on)...

推荐答案

您有两个选择

1-将它们另存为blob/图像/无论您选择的DB调用什么字节流
2-存储文件的路径，并将文件存储在文件系统中

选项2可以比装满doc，pdf等文件的数据库的开销快很多.

You have two options

1 - save them as a blob/image/whatever your chosen DB calls a stream of bytes
2 - store the paths to the files ,and store the files in your file system

Option 2 can be a lot faster b/c of the overhead of a DB full of doc, pdf, etc files.
