OTN Appreciation Day : Undo and Redo

On OTN Appreciation Day, let me say I like the Undo and Redo features of Oracle.  I name them together as they work together.

Undo also supports MultiVersionReadConsistency -- a great advantage of Oracle.

Redo, with Archive Logging, also supports Online Backups -- an absolute necessity.

These features have been around for almost 30 years now.

Here are some Quick and Rough Notes on Undo and Redo .
