Data ( /ˈdeɪtə/ DAY-tə, /ˈdætə/ DA-tə, or /ˈdɑːtə/ DAH-tə) are values of qualitative or quantitative variables, belonging to a set of items. Data in computing (or data processing) are often represented by a combination of items organized in rows and multiple variables organized in columns. Data are typically the results of measurements and can be visualised using graphs or images. Data as an abstract concept can be viewed as the lowest level of abstraction from which information and then knowledge are derived. Raw data, i.e., unprocessed data, refers to a collection of numbers, characters and is a relative term; data processing commonly occurs by stages, and the "processed data" from one stage may be considered the "raw data" of the next. Field data refers to raw data collected in an uncontrolled in situ environment. Experimental data refers to data generated within the context of a scientific investigation by observation and recording.
The word data is the plural of datum, neuter past participle of the Latin dare, "to give", hence "something given". In discussions of problems in geometry, mathematics, engineering, and so on, the terms givens and data are used interchangeably. Such usage is the origin of data as a concept in computer science or data processing: data are numbers, words, images, etc., accepted as they stand.
I've heard a lot of stories
So tell me if they're true
Oh I would die for you
Knowing that you're mine
You tell me that you're sorry
You say your heart is new
Oh I will cry for you
Call me and we'll dine
It's almost over Lorraine
Can you still feel the pain
Do you still want me to love you
It's such a funny day
Whoah oh oh
It's such a funny day
Tonight we sail for Paris
Where the streets are paved with gold
Your eyes have blessed my soul
Your lips, they've blessed the wine
We'll tame the Gulf of Lyons
I'll wed thee in Marseilles
We'll turn the moon to blood
If only there were time
It's almost over Lorraine
Can you still feel the pain
Do you still want me to love you
It's such a funny day
Whoah oh oh
