Detailed explanation-1: -description of each function presented in the DFD is contained in a process specification (PSPEC). DFD are used to represent data and the processes that manipulate it. of the software is contained in the control specification (CSPEC).
Detailed explanation-2: -A process specification (PSPEC) can be used to specify the processing details implied by a bubble within a DFD. The process specification describes the input to a function, the algorithm that is applied to transform the input, and the output that is produced.
Detailed explanation-3: -The CSPEC contains a state transition diagram that is a sequential specification of behavior. It can also contain a program activation table-a combinatorial specification of behavior. It is now time to consider an example of this important modeling notation for structured analysis.
Detailed explanation-4: -DFD is of two types: Logical DFD: Logical data flow diagram mainly focuses on the system process. It illustrates how data flows in the system.
Detailed explanation-5: -2. What describes the data and control to be processed? Explanation: Functions described in the statement of scope are evaluated and in some cases refined to provide more detail prior to the beginning of estimation.
