documentation

encompasses the narratives, flowcharts, diagrams, and other written materials that explain how a system works. This information covers the who, what, where, why and how of data entry, processing, storage, information output, and system controls.

narrative description

a written step-by-step explanation of system components and interactions.

data flow diagram

a graphical description of the source and destination of data, and how data are stored. describes the flow of data within in an organization.

data source

symbol in a DFD represent an organization or individual that sends or recieves data that the system uses or produces. represented by squares in a DFD. An entity can be both a source or destination.

data destination

symbol in a DFD represent an organization or individual that sends or recieves data that the system uses or produces. represented by squares in a DFD. An entity can be both a source or destination. Also referred to as a Data Sink.

data flow

represents the flow of data between processes, data stores, and data sources and destinations. data flow arrows are labeled to indicate the type of data being passed.

process

the processes that transform data from inputs to outputs are representes by circles. They are often referred to as Bubbles.

data store

is a temporary or permanent repository of data, should be descriptive. Represented by horizontal lines with the respective name recorded inside.

context diagram

the highest-level of DFD. Provides the reader with a summary-level view of a system. It depicts a dtat processing system and the external entities that are the sources and destinations of the systems inputs and outputs.

flowchart

is an analytical technique used to describe some aspect of an information system in a clear, concise, and logical manner. Use a standard set of symbols to describe pictorially the transaction processing procedures a company uses and the flow of data throu

flowcharting template

In the early days of flowcharts the symbols were drawn using a piece of hard, flexible plastic on which the shapes of symbols have been die cut. Most flowcharts today are done using software program.

document flowchart

a graphical description of the flow of documents and information between departments or areas of responsibility within an organization. Trace documents from its cradle to its grave.

internal control flowchart

document flowcharts that describe and evaluate internal controls are referred as this.

system flowchart

a graphical description of the relationship among the input processing, and output in an accounting information system.

program flowchart

a graphical description of the sequence of logical operations that a computer performs as it executes a program.

Many documentation tools are available to explain how a system works. Which tool provides a graphical description of the sources and destinations of data as well as data flow within the organization and the processes that transform and store that data?

Data flow diagram

A DFD is composed of which elements?

Data sources and destinations
Data flows
Transformation processes
Data stores
All of the above

Systems flowcharts

are an important systems analysis, design, and evaluation tool.
depict the relationships among the input, processing, and output of an AIS

A document flowchart is particularly useful

in analyzing the adequacy of control procedures.

What do the circles on a data flow diagram represent?

Transformation processes

Why are documentation tools important?

They are needed to determine how a system works
They are needed to evaluate internal control systems

The data flow diagram symbol which represents data flows is the

arrow
