mysql5

I have one dtabase in mysql.

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

Is that databse always present with one database.

I mean to say there is copy of information_schema for evry database present in mysql or in one mysql there is one table called inforemation_schema.

If i do something wronmg with table , how will that affect my current database
