DOAM NOIR

If we read the picture above, we'll read DOAM NOIR. What's that mean?, try it in google. Ok, that's picture is created by me. For what? I use this picture for remember me about Data Mining chapter Data. It's about Type and Properties Attributes, so I've made it so easy to remember. A little about data mining, type and properties attribute.

The following properties (operations) of numbers are typically used to describe attributes:

• Distinctness (= and ≠)
• Order (<, ≤, >, and )
• Addition (+ and -)
• Multiplication (* and /)

There are different types of attributes

• Nominal
• Examples: ID numbers, eye color, zip codes
• Ordinal
• Examples: rankings (e.g., taste of potato chips on a scale from 1-10), grades, height in {tall, medium, short}
• Interval
• Examples: calendar dates
• Ratio
• Examples: length, time, counts 

The type of an attribute depends on which of the following properties it possesses:

• Nominal attribute: distinctness
• Ordinal attribute: distinctness & order
• Interval attribute: distinctness, order & addition
• Ratio attribute: all 4 properties

So, you can see DOAM NOIR in red words.
