- These data can be organized into a specialized repository.
- These data can be easily stored in RDBMS table
- These data can have associated metadata and keywords.
- 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.
