Storing data

Hi,

I want to store data. Can a script write information to a already existing notecard or anything else or does it keep data only in memory ?
What happens if the sim gets rebooted does it keep this stored information or is it gone ? (as example : if have seen some TP systems with server and teleporter pads, the server script keeps the information of those tp pads how is this done then ? Info stored in script memory only ?

Will i need to use external database if i need to store alot of information ?

I tried going through the forum but cant seem to find exact answer too these questions.

your help would be greatly appreciated.

Thank you,
Ziyi

Scripts can't write to notecards. If you want to write to a secure database I would advise using llHTTPRequest to talk to an external server and store information there.
