Do the rules created get stored in a database / memory while the application is running or when it shuts down are all the rules lost?

To whom it may concern,

I was interested in using the expert system you created but I wanted to clarify whether the rules created by the user(s) are stored in some kind of long term memory, i.e. some database, or if when the application is shut down is everything lost?

Also if it does have the option to store everything to some database, do I just need to define the database connection in the application.properties file?
