What Is Big Data Big data refers to the collection and subsequent analysis of any significantly large collection of data that may contain hidden insights or intelligence (user data, sensor data, machine data). when analyzed properly, big data can deliver new business insights, open new markets, and create competitive advantages. Compared to the structured data in business applications, big data (according to IBM) consists of the following three major attributes:
• Variety—extends beyond structured data and includes semi-structure or unstructured data of all varieties, such as text, audio, video, click streams, log files, and more. • Volume—Comes in one size: large. organizations are awash with data, easily amassing hundreds of terabytes and petabytes of information. • Velocity—sometimes must be analyzed in real time as it is streamed to an organization to maximize the data’s business value.
