Oracle Intelligent Advisor (OIA) – formerly known as Oracle Policy Automation (OPA) – is a suite of decision automation software products for modeling and deploying business rules within the enterprise. Oracle Corporation acquired OPA in December 2008 when it purchased Australian software company RuleBurst Holdings, then trading as Haley. Oracle Intelligent Advisor transforms legislation and policy documents into executable business rules, for example for the calculation of benefit entitlements or discount amounts. Although OPA was originally developed for and sold to the public sector, it is now widely used in industry.
