Detailed explanation-1: -Yes, most big data sources, including Facebook, twitter etc., have unstructured data.
Detailed explanation-2: -Twitter certainly meets all of the definitions of “big data” but if we look closely, we find that good old traditional journalism is not far behind. The difference is that social media has aggressively marketed itself as “big data” while journalism has failed to rebrand itself for the digital era.
Detailed explanation-3: -Big data is defined as a complex and voluminous set of information comprising structured, unstructured, and semi-structured datasets, which is challenging to manage using traditional data processing tools. It requires additional infrastructure to govern, analyze, and convert into insights.
Detailed explanation-4: -Since unstructured data does not have a predefined data model, it is best managed in non-relational (NoSQL) databases.
