20. Data Source
A data source, in the context of
computer science and computer
applications, is the location
where data that is being used come
from. In a database management
system, the primary data source is
the database, which can be located
in a disk or a remote server.
21. THE DATA SOURCE
Internal
include data that exists
and is stored inside your
organization.
External
is data that was not
collected by your

face conversation
with the
respondent. It is
slow, expensive
and take people

fax and other methods.
These can be done while letting

also be made in natural setting
as well as in artificially created
environment.

•Blood pressure readings
•Number of optical shops in MM
Continuous Data
Discrete Data
•What was the severity of your flu?
•Low, Medium, or High
Ordinal Data
Nominal Data •Did you get a flu? Yes or No

44. Understanding Discrete vs. Continuous Growth
The key question: When does growth happen?
Discrete growth: change happens at specific intervals: eyeglass level
Continuous growth: change happens at every instant: bacteria colony
45. EXAMPLES OF CONVERSION OF
DISCRETE TO CONTINUOUS DATA
Measuring Attribute/Discrete Continuous
Gas Tank Empty/Full Gas Volume
Tree Heights Tall/Short Meters
Performance Poor/Average/Good Points/Pieces
Temperature # Days of Cold Average Temp.
Delivery No. of Late Time per Delivery
Scrap # of Pieces > Max Length Average Length

Meaning Unorganized information Processed data
What is it? It is just text and numbers. It is refined data.
Based on Records and Observations Analysis
Form Unorganized Organized
Useful May or may not be useful. Always
Specific No Yes
Dependency Does not depend on
information.
Without data,
information cannot be
processed.

the world for the past 100 years
2. The number of visitors to a website by
