In
this
paper,
we
will
use

2.2.3.1 Data flow diagram (DFD)
Data Flow Diagram (DFD) is a visualization of several data that
flows through an information system in a graphical representation (
A
data
flow
diagram
can also be used for the visualization of data processing (structured
design).
Furthermore,
DFD
is
also
applicable
in system
analysis
and
design as a technique to interpret the structured data flows that
are
primarily
concerned
with
automated
processes.
Basically,
DFD
uses
five basic symbols as shown in Figure 2.7 below based on analysis
data
that
retrieved
from

to
trace
and
describe
the movement of information such as:
2.2.3.1.1
External Agents/ Entities
External agents represent a destination of data flow
or
external
data
source.
Through external agents,
information from the process can be sent and received.
