Forward and Backward recovery

[life24]

Hi,

What is difference between forward recovery and backward recovery? Can you give me example?
Which software used backward recovery and which software used forward recovery?

When better we used in our software 'forward recovery' and when 'backward recovery'?

Those are pertinent to TRANSACTION data systems, and do not relate to normal PC operations.

That means ,this concept relevant to database systems?(DBMS?)

No - only to transactional databases. It does not apply to such data bases as created by Access.

These concept are available in programming? or only in transactional databases?

They serve no purpose except in a transactional database - and those are few and far between. An example is American Airlines old SABRE system. What exactly is it that you are trying to do?
