Coordinates: 36°30′03″N 94°15′53″W / 36. 500767°N 94. 264648°W
Area 71 is the unofficial title for Walmart’s 125, 000-square-foot (11, 600 m2) data center, located in Jane Missouri, near the Arkansas border. The facility has a capacity of over 460 terabytes (460 trillion bytes) of data. The facility is built directly on bedrock to better withstand natural and man-made disasters. It is self-sufficient, with generators and the capability to retain data connection with the Walmart network using copper wire, fiber optic cable, or satellite communications.
Sales patterns are analyzed here to identify trends in purchasing before major events (i. e. natural disasters, holidays) so that Walmart executives can better stock store shelves in anticipation of this event. 
Walmart uses the data facility to control many functions of its stores, including control of lighting, adjusting the climate control, and playing the in-store music. The data center maintains the computer system that employees use to “clock in” at every location, and provides email to keep employees informed of events pertinent to their job function.

How Data Centers Work – Computer | HowStuffWorks
Data centers are simply centralized locations where computing and networking equipment is concentrated for the purpose of collecting, storing, processing, distributing or allowing access to large amounts of data. They have existed in one form or another since the advent of the days of the room-sized behemoths that were our early computers, a data center might have had one supercomputer. As equipment got smaller and cheaper, and data processing needs began to increase — and they have increased exponentially — we started networking multiple servers (the industrial counterparts to our home computers) together to increase processing power. We connect them to communication networks so that people can access them, or the information on them, remotely. Large numbers of these clustered servers and related equipment can be housed in a room, an entire building or groups of buildings. Today’s data center is likely to have thousands of very powerful and very small servers running 24/cause of their high concentrations of servers, often stacked in racks that are placed in rows, data centers are sometimes referred to a server farms. They provide important services such as data storage, backup and recovery, data management and networking. These centers can store and serve up Web sites, run e-mail and instant messaging (IM) services, provide cloud storage and applications, enable e-commerce transactions, power online gaming communities and do a host of other things that require the wholesale crunching of zeroes and about every business and government entity either needs its own data center or needs access to someone else’s. Some build and maintain them in-house, some rent servers at co-location facilities (also called colos) and some use public cloud-based services at hosts like Amazon, Microsoft, Sony and colos and the other huge data centers began to spring up in the late 1990s and early 2000s, sometime after Internet usage went mainstream. The data centers of some large companies are spaced all over the planet to serve the constant need for access to massive amounts of information. There are reportedly more than 3 million data centers of various shapes and sizes in the world today [source: Glanz].
