Object-oriented database, a method for registering triggers for processing at end of a transaction

摘要

The disclosed invention is a computer-implemented method for registering triggers for processing at the end of each transaction occurring in a database. This method positions a class where a given object exists; and for each trigger in the class, a determination is made if the trigger is in a trigger list of an object link. If it is not, a determination is made if a given object is in an object link of a transaction. If it is not, then the given object is inserted into the object link of the transaction; and then the trigger is inserted in a list of the object link. These steps are repeated until all triggers in the class have been processed. A determination is next made if there is a superclass of the class. If yes, then a superclass, is positioned and the steps are repeated for each trigger in the superclass (i.e., polymorphic trigger). Finally, if no superclass of the class exist, then the method is exited.
