Location of rules created in web interface

Hello, I make interface generator. I change jsondb of items, things, links,meta. Now I need generate rules. I dont want to create file rules (/etc/openhab/rules) because rules load long time.
Can you tell me location of rules created in web interface

I think this is what you are looking for
/var/lib/openhab/jsondb/automation_rules.json

thanks, yes if i create rule, creates file automation_rules.json
