Differentiate between structured data and unstructured data. Give one suitable example of each and mention one reason why structured data is generally easier to analyse using conventional database tools.

Answer: Structured data is organised according to a fixed format, such as rows and columns in a student database. Unstructured data does not follow a predefined tabular structure, such as an audio recording or a free-form video. Structured data is generally easier to analyse with conventional database tools because its fields and data types are clearly defined.

Solution

Structured data has a well-defined schema, making searching, sorting and querying straightforward. Unstructured data lacks a fixed schema and usually requires specialised processing techniques.
