Data Flow Diagram For Online Banking System In Software Engineering Software Requirements SpecificationData flow diagrams (DFDs) are quite general and are not limited to problem analysis for software requirements specification. They were in use long before the software engineering discipline began. DFDs are very useful in understanding a system and can be effectively used during analysis. It views a system as a function that transforms the inputs into desired outputs. Any complex system will not perform this transformation in a single step, and data will typically undergo a series of transformations before it becomes the output. The agent that performs the transformation of data from one state to another is called a process (or a bubble). Thus, a DFD shows the movement of data through the different transformations or processes in the system. The processes are shown by named circles and data flows are represented by named arrows entering or leaving the bubbles. A rectangle represents a source or sink and is a net originator or consumer of data. A source or a sink is typically outside the main system of study. An example of a DFD for a system that pays workers is shown in Figure 3.6. In this DFD there is one basic input data flow, the weekly timesheet, which originates from the source worker. The basic output is the paycheck, the sink for which is also the worker. In this system, first the employees record is retrieved, using the employee ID, which is contained in the timesheet. From the employee record, the rate of payment and overtime are obtained. These rates and the regular and overtime hours (from the timesheet) are used to compute the pay. To compute the tax deduction, information from the tax-rate file is used. The amount of tax deducted is recorded in the employee and company records. Some conventions used in drawing this DFD should be explained. All external files such as employee record, company record, and tax rates are shown as a labeled straight line. The need for multiple data flows by a process is represented by a between the data flows. For example, if there is a between the two input data flows A and B for a process, it means that A AND B are needed for the process. In the DFD, for the process weekly pay the data flow hours and pay rate both are needed, as shown in the DFD. Similarly, the OR relationship is represented by a between the data flows. Figure 3.6: DFD of a system that pays workers This DFD is an abstract description of the system for handling payment.
