During run-time, each time an event of interest occurs on the Lotus Domino server (that is, when a Domino document is created, updated or deleted) the connector obtains the event data from Lotus Domino. ("How the connector works" describes this process in more detail.) The connector then maps the data to the business object definition to create a specific business object instance (commonly known as simply a "business object.") It then sends this business object to InterChange Server Express for processing, and the event information is in this way available to another application. The connector also receives business objects from InterChange Server Express. Business objects received from InterChange Server Express that originate from another application might request that Lotus Domino create, update or delete a document on the Lotus Domino server or that a document's existence be checked, or that an entire Domino document be sent back to InterChange Server Express, and from there to the requesting application.
