A data file that has no structured relationships between its records is known as a

• A. XML File
• B. Flat File
• C. Binary File
• D. Relational File

Answer: (B)

This question is about how data is organized in files with or without relationships between records. A flat file stores records in a simple, two-dimensional layout where each line is a record and fields are separated by delimiters like commas or tabs. There are no built-in links or nesting between records, so there’s no inherent structure tying one record to another. This contrasts with formats that encode relationships or hierarchy—XML uses a tree of elements with parent-child relationships, and a relational design uses tables connected by keys. A binary file is just raw bytes that may hold any kind of data, not a defined, relation-free row-and-field structure. So the description matches a flat file.
