Notification-based forward chaining

In an embodiment, a computer system determines that a first rule in a ruleset comprising a plurality of rules is to be executed, where the first rule includes a condition and an action that is to be performed when the first rule's condition is met. The computer system dynamically modifies the first rule's condition to include a portion of software code configured to monitor and receive notifications from a data-change notification system. The computer system executes the dynamically modified first rule and executes a second rule in the ruleset. The computer system receives a notification from the data-change notification system indicating that execution of the second rule's action has modified data values being monitored by the first rule's software code portion and that, as a result of the modification, the first rule is to be re-executed. The computer system also re-executes the first rule based on the received notification.
