Big Data The word big data has been used since the 1990s, and some people praised John Mash for approving this term. Big data usually contains data sets that exceed the size of ordinary software tools' ability to capture, organize, manage, and process data within a tolerable run time. The philosophy of big data includes unstructured, semi-structured and structured data, but focuses mainly on unstructured data. Big data "size" is a moving target, such as the data in 2012 ranges from tens of megabytes to many terabytes. Big data requires a suite of technologies with new forms of integration to reveal insights from diverse, complex and large-scale datasets. A definition of
2018 pointed out that "big data is a place where parallel computing tools are needed to process data", and pointed out that "this means that the computer science used has been changed significantly and affirmatively through parallel programming theory, losing some guarantees and guarantees.

In 2010, the profession was worth more than $100 billion and increased at nearly 10% per year: about twice as much as the entire software transaction. div font-size:16px;background-color:#ffffff;text-align:center;"=""p font-size:16px;background-color:#ffffff;"=""Xinglong economies are increasingly using data-intensive skills. There are 4.6 billion mobile phone users around the world, and 1 billion to 2 billion people access the Internet. Between 1990 and 2005, more than 1 billion people entered the middle class around the world, which meant that more people became more literate, which in turn led to an increase in information. The world's effective ability to exchange information through telecommunications networks was 281 PB in 1986, 471 PB in 1993, 2.2 EB in 2000, 65 EB in 2007, and predicted annual Internet traffic of 667 EB by 2014. According to an estimate, one-third of the information stored worldwide is in the way alphanumeric text and still image data, which is the most useful format for most big data applications. This also reveals the potential of unused data (i.e., video and audio content styles).
