I am looking for an SQL database of some type that is entirely based around the concept of time, just like those that are geo-centric, relationship-centric, etc.
My main wish is that I can make changes to the database as I go along, and then at any point run a query that essentially says, show me how the database looked at this date and time. I would prefer the SQL database have this functionality built in, instead of having to re-implement it using a log table and recording each and every transaction.
Am I hoping for a pipe dream?
Thanks!
EDIT: After some further research, it seems that a "temporal database" might be what I'm looking for. So any information on using one of those, if there are any good open-source ones available, etc., would be very helpful!
Oracle has Flashback. Closest I can think of on SQL Server requires snapshots, without resorting to restoring from transaction logs (requires full recovery model).
