Exam 6: System Mapping and Documentation
Which of the following is NOT an element of a process map?
C
Discuss what an entity is in terms of systems documentation and what the distinction of internal and external entity is dependent on.
An entity is any person or thing involved in the activities of a business process.Entities can be further classified as being either internal or external.The distinction between internal and external is dependent on (a)the process that is being documented and (b)the functions and tasks that are carried out by the entity.In the systems documentation context an entity is a person or thing that is involved in the execution of a process.As a rule of thumb,any entity that is not performing activities within the system scope can be considered an external entity while the ones that are performing activities and are within the system scope are internal entities.In summary,the key in determining whether an entity is internal or external is the activities that the entity performs.If the entity's sole activities involve sending or receiving data,they are considered external.In contrast,if the entity performs data processing or transformation,it is considered internal.
What are the differences between physical DFD and logical DFD?
The logical DFD is concerned with the processes that make up a system - essentially the question of WHAT is happening? In contrast,the physical DFD is focused on the entities that perform these processes - essentially the question of WHO is involved? So the bubbles in the logical DFD describe the processes and activities that occur within a system,while the bubbles in the physical DFD detail the entities involved in the system.Another difference to note between the logical and physical DFDs is the nature of the labels on the data flow arrows.In the physical DFD,these labels all referred to documents or physical items that flowed through the system.In the logical DFD,the flows tell us the type of information being sent.Also observe that,as in the physical DFD,the bubbles in the logical DFD are numbered.These numbers represent the order in which the processes occur,while the ones in the physical DFD indicate the order in which they take part in the process.

A description for a flowchart is as follows:
"The sales order and invoice are manually matched by the sales assistant and entered into the computer.The computer saves the data entered in the accounts receivable file."
The flowchart to best represent this would be:

-Refer to the physical DFD in the previous question.How many data stores are read by the sales person?

The ___________ is used to identify the system of interest.
______________ requires that the auditor shall obtain an understanding of the information system.
