Database Timelines
What are Database Timelines?
Database timelines introduce row versioning to the Recital database engine. Whenever a change is made to a table that is timeline enabled then delta changes are automatically recorded for each transaction.
Using Database Timelines
To enable database timelines all you need to do is issue SET TIMELINE ON command in your Recital configuration file.
The CLEAR TIMELINE command will reset a timeline.
There are 2 ways to view a timeline.
