mysql5

I have one database in mysql.

But when i log into phpMyAdmin , it shows another database called information_schema.

Is that database always present with one database?

I mean to say is there a copy of information_schema for every database present in mysql or is there one database called inforemation_schema per mysql server?

If i modify this information_schema database how will that affect my current database?
