| Question 3 |
In transform analysis, input portion is called :
| Afferent branch | |
| Efferent branch | |
| Central Transform | |
| None of the above |
Question 3 Explanation:
Transform Analysis:
It identifies the primary functional components (modules) and the high level inputs and outputs for these components.
1. Input
2. Logical processing
3. Output
The input portion of the DFD includes processes that transform input data from physical (e.g. character from terminal) to logical forms (e.g. internal tables, lists, etc.). Each input portion is
called an afferent branch.
The output portion of a DFD transforms output data from logical to physical form. Each output portion is called an efferent branch. The remaining portion of a DFD is called the central transform.
It identifies the primary functional components (modules) and the high level inputs and outputs for these components.
