Can anybody explain the purpose of SWRL rules. As far as I have understood, SWRL rules are same as stored procedures in SQL. I have made a few rules, but don't know how to utilize them in my application through query. I don't know whether I am thinking in the right way the SWRL rules are meant for, or not. Please show me the correct way of using them.

Look at this rule:

Patient(?x) ^ hasValue_heartrate(?x, >160) -> Sick(?x)

In my ontology I have Patient class, but no Sick class & not even hasValue_heartrate property. So should I have to create these? Or how can I use above rule in my ontology?
