Abstract
Triggers for automatically starting an extract process in response to the committing of update data to a repository by an update process. In one embodiment, triggers are associated with particular extract processes and are started upon the committing of update data to the repository by an update process. Upon being started, each trigger determines whether any of the update data is within the extract view of the extract process that it is associated with and, if so, evaluates a predetermined condition specified for the trigger. If the condition is satisfied, the trigger translates the update data within the extract view into the extract view and starts the extract process. In another embodiment, triggers are bound to repository entities within the view of an extract process and are started upon the updating of the corresponding entities. Upon being started, each trigger evaluates a predetermined condition specified for entity post-image and, if the condition is satisfied, adds the post-image to data being accumulated for the extract process. Upon the commitment of the update, all extract processes for which data has been accumulated are started after making available the data accumulated for the process. In yet another embodiment, if the condition specified for the entity post-image is satisfied, the trigger executes a trigger query against the updated entity instance to dynamically generate a list of triggers which are then executed.
