Some sites don't use a database to store data at all, such as the bai-du you're using now, although it's pretty spammy;

There are small sites that are static and don't use databases;

And there are some sites that put files such as images in the database, so you're telling me that every month, how big is the data he has? How much data do you think he has every month? So it has to do with mass storage and so on;
