What is big data? Big data refers to datasets whose volume, velocity, variety, and complexity exceed the ability of commonly used software tools to capture, process, store, manage, and analyze. Big data is the combination of different types of data:
• Unstructured—data communicated every day by email, phone, text, tweet, and video
• Semi-structured—data generated by machines
• Structured—data traditionally stored in databases, such as account information and credit card transactions for example, log files
The challenge of big data is to efficiently and effectively capture, store, manage, and analyze 100 percent of the data to drive business insight and timely decisions.
