Big data is a huge amount of diverse information that comes in ever-increasing volumes and at an ever-increasing speed.
Big data can be structured (often numeric, easily formatted and stored) or unstructured (more free-form, less quantifiable).
Almost every department in a company can use the results of big data analytics, but handling this clutter and noise can be problematic.
Big data can be collected from public comments on social networks and websites, voluntarily collected from personal electronics and applications, through questionnaires, product purchases and electronic registrations.
Big data is most often stored in computer databases and analyzed using software specially designed to process large and complex data sets.
