Definition :
Transaction is a methodology implemented by EJBs to manage the business data accurately and reliably.

Can we say like this in one sentence?

Puthriah,
A transaction is more than that. A transaction can be used by other things besides EJBs (like jdbc.) It also ensures the ACID properties. You can google "ACID transaction" for more details on this.
