Help required to draw a DFD for the following scenario:

A bank manager actor provides new account details to the Open Account process which results in customer details being persisted in the Customer Database data store and account details being persisted in the Account Database data store. The Open Account process can read in data from the Bank Manager interface and write out data to the Customer Database and Account Database data stores in no particular order. A customer actor using the Online Banking Login process must provide some data in the form of a set of login credentials such as a user name and password. A customer actor can receive a money amount from the Withdraw process and can supply a money amount to the Deposit process; in either case causing (although this causation cannot be explicitly modeled) an account balance update to the Account Database data store. A customer actor can initiate the Transfer Funds process, to which he or she must provide an account destination and money amount. The Transfer Funds process can send a money amount to another bank via the Other Bank interface. Just like the customer actor, a third party actor can make use of the Deposit process (but obviously not the Withdraw process) by supplying a money amount.
