The systems analyst of Chandrabhaga Urban Bank has prepared, for the cheque-return module, the picture reproduced as Figure 2. It shows the clearing house and the branch as sources and destinations of data lying outside the system; the validation of the return memo and the raising of the return charge as processes performed within it; the presentation register as a place where data comes to rest; and arrows carrying named data from each of these to the next. The picture names no programming language, no le organisation, no sequence of execution and no hardware; it says only what data enters, what is done to it and where it goes. A diagram of that description, which shows the ow of data through a system by means of processes, data stores, external entities and data ows, is called a:
