Answer 1

You could make use of the FLASHBACK QUERY .

I answered a similar question here https://stackoverflow.com/a/27309814/3989608

You could go back as far as depending on the settings of the UNDO_RETENTION parameter.

A quote from T.Kyte regarding flashback query:

flashback query has been enabled in the database for many many many years.
We call it Multi-versioning and it gives us our consistent read and non-blocking reads.

That means -- you've been doing flashback query for years.

You do not need to "enable it", it is an intrisic feature/function of the database that you cannot in any way "disable"!

It is ALWAYS on.
