Which term best describes data collection that is massive and unstructured?

• A. Data mining
• B. Big Data
• C. Data broking
• D. Agency

Answer: (B)

Big Data describes data that is both massive in scale and unstructured in nature. Unstructured data includes things like social media posts, emails, photos, videos, and sensor streams that don’t fit neatly into predefined tables. Because of the sheer volume and variety, traditional data processing tools struggle to capture, store, and analyze such data; specialized frameworks and technologies are used to handle it. Data mining is about discovering patterns inside data, not describing the data’s characteristics or collection type. Data broking involves selling data about people or organizations. An agency is just an organizational body, not a descriptor of data. So the term that best fits data collection that is both enormous and unstructured is Big Data.
