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.
EXPLAIN IT AWAY
Light the signal fire
I said I'm coming home
I don't remember if I had something here
Or I can't complain about it
I got a piece of perfect
Always on my mind I see her now
And I don't know if it's that
I don't care or she won't care
Explain away and I do
The picture perfect thing
I would light the time
I could mean so much to you
Explain away and you do
The picture perfect dream
Lies and reasons hide
What it is you mean to me
Who she really is
I forgot to check this time
I got to be obtrusive
It's my life to be hung up about it
And maybe she'll be happy
If I breach the walls around her
And I don't know if it's that
I don't care or she won't care
CHORUS
So don't complain to me
It's you you really want to talk to
I got ideas to lend
But I'm afraid the cost to reach you
One look reality
And here I am to heal your pieces
And all there is to do today
