Database timelines provide row versioning for Lianja database tables. Whenever a change is made to a table that is timeline enabled, delta changes are automatically recorded for each transaction. Changes made to any tables that are timeline enabled can be undone much like you would undo changes to program code that you edit in a text editor. The global setting SET SYSTIMELINE must be ON to use the SET TIMELINE command or Timeline Attributes to enable timelines for an individual table or application. SET SYSTIMELINE is ON by default.
