In information technology, big data is a loosely-defined term used to describe data sets so large and complex that they become awkward to work with using on-hand database management tools. Difficulties include capture, storage, search, sharing, analysis, and visualization. The trend to larger data sets is due to the additional information derivable from analysis of a single large set of related data, as compared to separate smaller sets with the same total amount of data, allowing correlations to be found to "spot business trends, prevent diseases, combat crime."
Though a moving target, as of 2008[update] limits were on the order of petabytes to zettabytes of data. Scientists regularly encounter limitations due to large data sets in many areas, including meteorology, genomics,connectomics, complex physics simulations, and biological and environmental research, The limitations also affect Internet search, finance and business informatics. Data sets grow in size in part because they are increasingly being gathered by ubiquitous information-sensing mobile devices, aerial sensory technologies (remote sensing), software logs, cameras, microphones, radio-frequency identification readers, and wireless sensor networks. The world's technological per-capita capacity to store information has roughly doubled every 40 months since the 1980s; as of 2012[update], every day 2.5 quintillion (2.5×1018) bytes of data were created.
Big is a 1988 romantic comedy film directed by Penny Marshall and stars Tom Hanks as Josh Baskin, a young boy who makes a wish "to be big" to a magical wishing machine and is then aged to adulthood overnight. The film also stars Elizabeth Perkins, and Robert Loggia and was written by Gary Ross and Anne Spielberg.
Big was the latest, and most successful, of a series of age-changing comedies produced in the late 1980s; the others being: Like Father Like Son (1987), 18 Again! (1988), Vice Versa (1988), the Italian film Da grande (1987).
After being told he is too short for a carnival ride while attempting to impress an older girl (Kimberlee M. Davis), 12-year-old Josh Baskin (David Moscow) from Cliffside Park, New Jersey goes to a wishing machine called Zoltar Speaks, and wishes that he was "big." His wish is granted, but he finds out that the machine is unplugged, and backs away. By the next morning he is shocked to discover that he has been transformed into a 30-year-old man (Tom Hanks), and when he goes back to the wishing machine he finds that the carnival has already left. Fleeing from his mother (Mercedes Ruehl), who thinks he is a strange man who has kidnapped her son, Josh then finds his best friend, Billy Kopecki (Jared Rushton), at the school they both attend; Billy is shocked at first, but Josh convinces him of his identity by singing a secret song that only the two of them know. With Billy's help, he learns that it would take a couple of months to find the Zoltar Speaks machine, so Josh rents a flophouse room in New York City and gets a data entry job at MacMillan Toy Company.
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.
How could you know, how could you know'
That those were my eyes
Peepin through the floor, it's like they know
It's like they know I'm looking from the outside
And creeping to the door, it's like they know
And now they coming, yeah, now they coming
Out from the shadows
To take me to the court because they know
That I shut this down, cause they been watching all my windows
They gathered up the cause they-
You understand, they got a plan for us
I bet you didn't know that I was dangerous
It must be fate, I found a place for us
I bet you didn't know someone could love you this much
How could they know, how could they know
What I been thinking'
Like they're right inside my head because they know
Because they know, what I been hidin'
They're right under my bed, they're in control
Here they come, yeah here they come
Out of the shadows
To take me to the club because they know
That I shut this down, cause they been watching all my windows
They gathered up the warrant 'cause they-
And I've gotta get out of here
Sink down, into the dark
Keep on running
And I've gotta get out of here, (keep on running)
Sink down, into the dark
You understand, they got a plan for us
I bet you didn't know that I was dangerous
It must be fate, I found a place for us
I bet you didn't know someone could love you this much
Nobody's listening when we're alone
Nobody's listening, there's nobody listening,
No one can hear us when we're alone,
No one can hear us, no, no one can hear us
And I've gotta get out of here
Sink down, into the dark
Keep on running
And I've gotta get out of here
Keep on running
Sink down, into the dark
You understand, they got a plan for us
I bet you didn't know that I was dangerous
It must be fate, I found a place for us
I bet you didn't know someone could love you this much
