You can google around and find pages like this: http://www.java-tips.org/java-ee-tips/enterprise-java-beans/introduction-to-the-java-transactio.html

but the bottom line is: a transaction is a set of operations which must all succeed or all fail and be reversed (rolled back).

The obvious example is banking: if you transfer money from savings to checking, both updates had better occur, or neither, otherwise there will be an error.
