I have found that Teradata uses:
READ_ISOLATION_LEVEL= ACCESS|READ|WRITE
How it correspond to usual read commited/dirty in usual databases? Thanks.

Not sure if this addresses your question entirely:
ACCESS
locking would allow dirty reads allowsWRITE
lock to be in place.READ
locking allows only committed reads and can blockWRITE/EXCLUSIVE
locks while reading data.WRITE
lock preventsREAD
locks from access data but allowsACCESS
(dirty read) lock to access data.
