[DB-SIG] Which db mapping tool?

[Jekabs Andrushaitis]

Basically there are alot of events that could trigger the change of rowid
for the record,
since rowid is a reference to the physical data block in the tablespace of
the said
table row. It can even change if the row is updated - Oracle might decide to
move
the row physically around without you even knowing it. Although accessing
records
by using rowid is the fastest possible way, using unique indexes is not much
slower.
