Big Data refers to a huge amount of structured and unstructured data, so huge that it is difficult to work with using normal database and software techniques. In most companies the amount of data is too large or moves too fast or exceeds current processing power. Big data can be analyzed to gain insights that lead to better decisions and strategic business moves. While the term “big data” is relatively new, the act of storing large amounts of information for study is quite old. Big data is associated with the three v's: Volume. We collect data from business transactions, social media, and information from sensors or machine-to-machine data. In the past, storing them would have been a problem, but new technologies like Hadoop have made it easier. Speed. Data flows flow at high speed and must be managed in a timely manner. RFID tags, sensors and smart meters are driving the need to manage torrents of data in near real-time. Variety.

However, you need to connect and correlate relationships, hierarchies, and data links, otherwise your data can spiral out of control. Big Data has the potential to help companies improve operations and make faster, smarter decisions. The data comes from a variety of sources including email, mobile devices, applications, databases, servers, stock market data and financial transactions. This data, once captured, formatted, manipulated, stored, and then analyzed, can help a business gain actionable insights to increase revenue, acquire or retain customers, and improve operations.

You can take data from any source and analyze it to find answers that enable 1) cost reduction2) time reduction3) new product development and optimized offerings4) intelligent decision making.
