All of your recent questions sound like job interview questions. Who's going to do the job for you once you get it?
As for the database question, the words you've presented can't possibly be precisely how it was asked, and whatever changed from when it was asked, and when you paraphrased it for us has lost the element of making sense.

Wat would be the best way..?
How many way are there to do it? If you can name all the ways, I'll pick the best one
but using DBI'S prepare() ,execute can we do the above operations at once?
What does "at once" mean to you?
If yes how? ..plz answer!
See DBI its full of examples; See also Tutorials->Database Programming->DBI recipes, its like stuff from the DBI docs (the examples)

“A database transaction” is an all-or-nothing boundary: either everything happens, or nothing does. Depending on the system, transactions may or may not be nested. Bulk operations usually depend on intelligent use of transactions to avoid time-consuming “physical commits.”
Yes, this sounds like a homework question. (Or, a question posted by a far-away offshore contractor who quoted the lowest price?) Short answer is ... “Google it.” And, pray. Plenty of stuff has already been written on this subject, which really has nothing specifically to do with Perl or any other language.
