FLOWCHART EXAMPLE OF FLOWCHART

A diagram is a two-dimensional geometric symbolic representation of information according to some visualization technique. Sometimes, the technique uses a three-dimensional visualization which is then projected onto the two-dimensional surface. The word graph is sometimes used as a synonym for diagram.

Here term diagram in common sense can have two meanings.

visual information device : Like the term "illustration" the diagram is used as a collective term standing for the whole class of technical genres, including graphs, technical drawings and tables.

specific kind of visual display : This is only the genre, that show qualitative data with shapes that are connected by lines, arrows, or other visual links.

a form of visual formatting devices a display that do not show quantitative data,

but rather relationships and abstract information

with building blocks such as geometrical shapes connected by lines, arrows, or other visual link.

There are at least the following types of diagrams:

• Graph-based diagrams: these take a collection of items and relationships between them, and express them by giving each item a 2D position, while the relationships are expressed as connections between the items or overlaps between the items; examples of such techniques:

tree diagram network diagram flowchart Venn diagram existential graph

•Chart-like diagram techniques, which display a relationship between two variables that take either discrete or a continuous ranges of values; examples:

histogram bar chart pie chart function graph scatter plot

•Other types of diagrams-

train diagram exploded view

population density map

Pioneer plaque

A graphical representation of the sequence of operations in an information system or program. Information system flowcharts show how data flows from source documents through the computer to final distribution to users. Program flowcharts show the sequence of instructions in a single program or subroutine. Different symbols are used to draw each type of flowchart.

Flowcharts can be modelled from the perspective of different user groups (such as managers, system analysts and clerks) and that there are four general types:

Document flowcharts, showing controls over a document-flow through a system

Data flowcharts, showing controls over a data flows in a system

System flowcharts showing controls at a physical or resource level

Program flowchart, showing the controls in a program within a system

Eight steps that insure complete preparation and execution of a flowchart are-

Research the problem Decide on the method of solution Plan the solution Outline the system by drawing the system

flowchart Check the system flowchart Draw a detailed program flowchart for each

program Check the program flowchart Test the program flowchart and system flowchart

by using data that has been prepared

The flow of the flowchart should be from top to bottom and from right to left

Use meaningful descriptions in the symbols If the flowchart is complex ,connectors

should be used to reduce the number of flow lines. Avoid intersecting flow lines.
