Well, from what I've read, mysql differentiates between the number of users and the number of queries those users are executing at the same time. I couldn't find any exact figures, but I did find that it basically boils down to how the db was set up and what hardware it is running on. Thus, I became curious about the particular setup here at dreamhost where I am a customer.
I teach at a school where I am interested in using a mysql database for a project. I'm currently in the research phase, trying to determine how realistic it might be, but I am essentially looking at 300 students who will log in and perform queries at the same time.
Aside from my particular needs, I became curious about the power of mysql from a purely geeky standpoint. I'm far from knowledgeable in this subject, but very interested nonetheless.
Thank you to any replies.
