The database and ajax younger brother recently tried to write an online chat room and encountered a chat record storage problem. Could you tell me if I have a database? my classmates asked me to store files and read them in ajax mode. He said that the existence of a database has a great impact on the performance, so I 'd like to ask, whether the file exists directly or in the database, or do you have any awesome methods to teach me? thank you very much ------ solution -------------------- put it in xml-database and ajax

Nice to put in xml
------ Solution --------------------
Open the directory where the database stores data and you will see files one by one. We can see that the database also stores data in files.
Since all files are read and written, how much impact on performance?
------ Solution --------------------
I personally think that saving files is less performance than the database (the chat room may not be able to see it, and it feels like a large amount of data)
It's just that the content in the chat room is a temporary session, so I feel that there is no need to store the database!
You can use xml!
