FlashbackNone

FlashbackNone refers to a setting in certain database systems, particularly Oracle, where no historical data is stored for transactions. When this setting is activated, only the current state of the data is maintained, meaning that once data is changed, the previous version is lost. This approach prioritizes performance and simplicity but at the cost of being unable to recover previous states or track changes over time. In practical terms, if a mistake is made, it cannot be undone or traced back, making it crucial for users to be careful when working with data under this setting.
