Preffered Answer:

Direct Delta: In this METHOD, extraction data from DOCUMENT postings is transferred directly to BW delta queue.

Queued Delta: In this method, extraction data from document postings is collected in an extraction queue, from which a periodic COLLECTIVE run is used to transfer the data to BW delta queue. o The transfer SEQUENCE and the order in which the data was created are the same in both Direct and Queued Delta.

Unserialized V3 Update: In this method, the extraction data is written to the update tables and then is transferred to the BW delta queues WITHOUT taking the sequence into account.
