A user may merely need to specify various states of transactions and actions to be performed upon reaching a state for the corresponding transaction, and a front end block may automatically perform an action when the corresponding state is reached. Each action may indicate any necessary movement of data to a new storage portion. As a result, a programmer can be shielded from various details (e.g., which database to store the data in, data format conversions) in (developing the code for) processing the transactions.
