An Indian e-commerce company collects customer data in the form of images of products returned, free-text reviews, and a table of orders with fixed columns. Which statement correctly classifies this data?
The order table is structured data because it follows a fixed row and column schema, while product images and free-text reviews are unstructured data since they lack a predefined format. Digital storage alone does not make data structured.
- AAll three are structured data because they are stored digitally
- BThe order table is structured, while images and free-text reviews are unstructuredCorrect
- CImages and reviews are structured, while the order table is unstructured
- DAll three are semi-structured because they relate to the same customer
Explanation
Data held in fixed rows and columns, like the order table, is structured. Images and free text have no predefined schema, so they are unstructured. Storing data digitally does not make it structured, so the first option is wrong.
