Creating a custom item system. I need a pointer.

[Jiroxys7]

Okay, so i'm learning SQLite (great guide, chris. cant wait to see the rest of it!)
Thing is, I want my item system to be able to have varying stats, such as a semi-random durability value. Can SQLite support this? or would I be better off with another system?

Also, if i stick with SQLite, what are these security issues, and how should i go about preventing them?

edit: Lastly, if it make any difference, I'm looking to be able to incorporate a bag size limit too.
