Why is newbienoob saving to mysql table variable ID in his tut? For what is it needed?

Searching through numbers is much faster than searching through text. It also comes into play when creating relations to different tables (yes, MySQL is a relational database!). You want to avoid duplicate data at all costs. Duplicating the name into different tables is a terrible practice. Other than that, the name may be changed. The ID won't.

I was just wondering if I cant just use check for names but now I know through numbers its faster.
