[rules-users] Moving rules from DB to a rules engine

Hi, This is my first post. We have a facility in our Java web application to upload SQL queries to the Oracle DB. These queries are not controlled or audited. There are queries the are several pages long. Some of these queries are configured to fire one after the other to approve our workflow. When our workflow fires these query rules create an enormous load on the system. My concern at this time is that we are using the DB as a primitive and uncontrolled rules engine. I am interested in using a proper rules engine. What should my approach be ? Can I look at case studies or just Drools documentation ? Thanks.
