Explain the difference between structured and unstructured data.
Structured data is always text-based.
Structured data is organized in a predefined format, while unstructured data lacks a specific format.
Structured data is disorganized and messy.
Unstructured data is always stored in a database.
How does semi-structured data differ from structured data?
Structured data is more flexible than semi-structured data.
Semi-structured data does not fit into a rigid tabular structure like structured data.
Semi-structured data is always perfectly organized.
Semi-structured data is always stored in a database, unlike structured data.
What are the main challenges faced in analyzing Big Data?
