Hi Simon,

One of my colleague asked me if SQLite have any "Database redundancy 
support"?
So i was trying to correct him saying that Data redundancy is an issue 
and why should an RDBMS  support an issue?
So from his words what i understood was a mechanism like 'Managed Backups'.
That was what i tried to convey by calling it Automatic Backup.

Another doubt is like :
When you say sorting contents in the DB, is this the same as Querying?

Thanks & Regards,
Sen
