The present invention provides a method for optimizing the processing of backend transactions by receiving related transactions for processing from a program executing on a computer, and prioritizing the related transactions by determining: a degree of necessity for each related transaction; and which of the related transactions can be executed in parallel by determining which related transactions depend upon the successful completion of a transaction. The method further includes executing all related transactions that can be in parallel, and do not depend upon the successful completion of a transaction, executing related transactions that depend upon the successful completion of a transaction if it successful completes, canceling execution of any of the related transactions that depend upon the transaction that did not successful complete and has the degree of necessity of critical or best effort, and returning to the program any data resulting from the execution of the related transactions.
