Define functional primitives and explain how they are used.

When a set of DFDs is created for a system, the processing logic is broken down into smaller units, called functional primitives, which programmers will use to develop code. A functional primitive is a process that consists of a single function that is not exploded further. The logic for a functional primitive is documented by writing a process description in the data dictionary. Later, when the logical design is implemented as a physical system, programmers will transform each functional primitive into program code and modules that carry out the required steps. Deciding whether to explode a process further or determine that it is a functional primitive is a matter of experience, judgment, and interaction with programmers who must translate the logical design into code.
