US Patent 7818305 Hierarchical triggers for database

The present invention introduces the concept of a super-trigger to allow for multi-level hierarchical triggers in a database application. The super-trigger may be created by identifying one or more triggers as sub-triggers, and defining a condition in the super-trigger, the result of the condition depending from a result of one or more of the sub-triggers. Upon execution, information may be retrieved regarding a result for each of the sub-triggers. The condition may then be evaluated using these results, and an action may be performed if the condition is met.
