Question-2: Which of the following are true for semi-structured data?

1. These data can be organized into a specialized repository.
2. These data can be easily stored in RDBMS table
3. These data can have associated metadata and keywords.
4. JSON and XML data are the example of semi-structured data

Answer: C, D

Exp: Yes, semi-structured data cannot be sired in a specialized repository like RDBMS table or Spread sheets. They are generally stored in individual documents. XML and JSON are the examples of semi-structured data. These data can have associated metadata like schema in XML and possibly keywords etc. So you cannot say that semi-structured data cannot have schema.
