This document discusses different types of flow charts used in documentation techniques, including data flow diagrams, entity relationship diagrams, document flow charts, system flow charts, and program flow charts. It provides descriptions of each type of flow chart, what they depict, and their purposes. Document flow charts show manual systems and processes, system flow charts show computer aspects and relationships in a system, and program flow charts show the logic and relationships between specific computer programs. The document emphasizes the importance of properly labeling, using correct symbols, and including additional descriptions for clarity in flow charts.

6.  A flowchart is a graphical representation of
a system that describes the physical
relationships between its key entities.
 Flowcharts can be used to represent manual
activities, computer processing activities, or
both.
 There three types of Flow charts
 Document
 System
 Program

7.  A document flowchart is used to
depict the elements of a manual
system, including accounting records
(documents, journals, ledgers, and
files), organizational departments
involved in the process, and activities
(both clerical
 and physical) that are performed in
the departments.

9.  System flowcharts portray the computer
aspects of a system.
 They depict the relation-ships between input
(source) data, transaction files, computer
programs, master files, and output reports
produced by the system.
 System flowcharts also describe the type of
media being used in the system, such as
magnetic tape, magnetic disks, and
terminals.

11.  shows the relationship between two computer
pro-grams, the files they use, and the
outputs they produce. However, this level of
documentation does not provide the
operational details that are sometimes
needed. For example,
 an auditor wishing to assess the correctness
of the edit program’s logic cannot do so from
 the system flowchart. This requires a
program flowchart.

13.  The flowchart should be labeled to clearly
identify the system that it represents.
 The correct symbols should be used to represent
the entities in the system.
 All symbols on the flowchart should be labeled.
 Lines should have arrowheads to clearly show the
process flow and sequence of events.
 If complex processes need additional explanation
for clarity, a text description should be included
on the flowchart or in an attached document
referenced by the flowchart.

 Real time system
 Batch systems
 Secondary storage
 Pre-reading will be appreciated and will give
you more benefit…
