Study on Causes and Issues of Big-Data

An increasing amount of data is becoming available on the internet. Each and every one of us is constantly producing and releasing data about ourselves. We do this either by moving around passively - our behavior being registered by cameras or card usage - or by logging onto our PCs and surfing the net. The volumes of data make up what has been designated 'Big Data' -- where data about individuals, groups and periods of time are combined into bigger groups or longer periods of time. The amount of data in our world has been exploding. Companies capture trillions of bytes of information about their customers, suppliers, and operations, and millions of networked sensors are being embedded in the physical world in devices such as mobile phones and automobiles, sensing, creating, and communicating data. Multimedia and individuals with smart phones and on social network sites will continue to fuel exponential growth. Big data?large pools of data that can be captured, communicated, aggregated, stored, and analyzed?is now part of every sector and function of the global economy. Like other essential factors of production such as hard assets and human capital, it is increasingly the case that much of modern economic activity, innovation, and growth simply couldn’t take place without data.
