Page_title module actually tells you the MySQL command to create a table but other modules like Ping does not

The readme.txt file for the Page_title module offers the actual syntax that needs to be executed in the PHPMyAdmin to add a new table to a database. But in other modules there is no help whatsoever in what to do. I have downloaded the Ping module but find no help at all in creating the tables in my database. Why is this?
