[rules-users] [Drools Interest] Dynamic rule loading from DB

[Mauricio Salatino]

Yes, storing the rules in a database or storing them in a repository as
guvnor will allow you to configure the rules any time you want.
It would be nice to know about your object model to be able to describe the
better approach for writing rules against it.
