将用户数据存储在csv文件与数据库中

Question

I am making a site where user can register and make posts using PHP. Currently I have 2 tables in a db, and lots of csv files. Both of them together hold, username, password etc. and counters, posts, date etc respectively.

My Question is If it is a good idea to go with two storage systems. Of course i can store all of it in a database. My main concern is fast read & write capability.

Also note that some data is required frequently, and some is required rarely, if i have to divide the data b/w csv & db, what can be better way?

Answer 1

仅使用DB，而不是CSV。
