1. Flowchart
PREPARED BY: GRACETYL MAE B. CALAGO

2. What is a flowchart?
 a type of diagram that represents an
algorithm, workflow or process, showing the
steps as boxes of various kinds, and their order
by connecting them with arrows
 diagrammatic representation that illustrates a
solution model to a given problem

3. What is a flowchart?
 used in analyzing, designing,
documenting or managing a
process or program in various
fields
 described as "cross-functional"
when the page is divided into
different swimlanes describing
the control of different
organizational units.

4. Types of Flowchart
Document Flowchart
Data Flowchart
System Flowchart
Program Flowchart
shows controls over a document-flow through a system
shows controls over a data-flow in a system
shows controls at a physical or resource level
shows the controls in a program within a system

5. Flowchart Symbols
Terminator
Process
Decision
Indicates the beginning or end of a
program flow in your diagram
Indicates any processing function
Indicates a decision point between
two or more paths in a flowchart

6. Flowchart Symbols (cont.)
Delay
Data
Document
Indicates a delay in the process
Can represent any type of data (input
and output) in a flowchart
Indicates data can be read by
people, such as printed output

7. Flowchart Symbols (cont.)
Multiple
Documents
Subroutine
Preparation
Indicates multiple documents
Indicates a predefined (named)
process, such as a subroutine or a
module
Indicates a modification to a process,
such as setting a switch or initializing a
routine

8. Flowchart Symbols (cont.)
Manual
Loop
Indicates data that is displayed for
people to read, such as data on a
monitor or projector screen
Indicates any operation that is
performed manually (by a person)
Indicates a sequence of commands
that will continue to repeat until
stopped manually
Display
Manual Input

9. Flowchart Symbols (cont.)
Connector
Indicates the start of a loop. Flip the
shape vertically to indicate the end of
a loop.
Indicates any data of stored data
Indicates an inspection point
Loop Limit
Stored Data

10. Flowchart Symbols (cont.)
Off-page Connector
Use this shape to create a cross-
reference and hyperlink from a
process on one page to a process on
another page
Internal
Storage
Indicates an internal storage device

11. Flowchart Symbols (cont.)
Or
Logical OR
Logical AND
Indicates a step that organizes data
into a standard format
Summing
Junction
Collate

12. Flowchart Symbols (cont.)
Sort
Indicates a step that organizes items
sequentially
Indicates a step that combines
multiple sets into one
Indicates a list of information with a
standard structure that allows for
searching and sorting
Merge
Database

13. EXAMPLES

14. Solve the equation 2x2 + x + 5 for all
x between 5 and 10 inclusive.
Start Set variable x = 5
x <= 10?
compute 2x^2 + x + 5
add 1 to x End
Print answer
Yes
No

15. Create a flowchart to display all
numbers between 1 and 10 inclusive
Start Set i = 1
i <= 10?
i = i + 1 End
Print i
Yes
No
