Hi
Begin transaction will save all the data changes made between begin and end transaction.
Tableupdate makes a change to the data on the base table, as it saves it to the disk.
Begin transaction locks all the changes tableupdate makes on base tables, and unlocks them on end transaction command. On rollback command it restores data on base tables to the previsious state before tableupdate and of course unlocks them.
The data on buffered cursor remains changed, so you have to put tablerevert after rollback command.
