Big data and its Characteristics

Answer 1

Big data:

The generation of data sets of enormous volume and complexity is called Big Data.

Characteristics of Big Data:

• Volume: The most prominent characteristic of big data is its enormous size. If a particular data set is of such a large size that it is difficult to process it with traditional DBMS tools, it can be termed big data.
• Velocity: It represents the rate at which the data under consideration is being generated and stored. Big data has an exponentially higher rate of generation than traditional data sets.
• Variety: It asserts that a data set has varied data, such as structured, semi-structured, and unstructured data. Some examples are text, images, videos, web pages, and so on.
• Veracity: Big data can be sometimes inconsistent, biased, and noisy or there can be an abnormality in the data or issues with the data collection methods. Veracity refers to the trustworthiness of the data because processing such incorrect data can give wrong results or mislead the interpretations.
• Value: Big data is not only just a big pile of data but also possesses to have hidden patterns and useful knowledge which can be of high business value.
