The OLTP Abstract Machine ● Online programs are initiated via a message and produce a reply message within seconds ● The TP monitor and DB manager provide: – rapid dispatching via pre-allocated resources, – efficient concurrent execution – distribution over multiple processors – record level data access and other services ● Consolidated as the “transaction abstraction” – Individual transactions usually single threaded ● OLTP supports most consumer transactions today 12
