Describe metadata.
What will be an ideal response?
Metadata is information that describes data in a database. A raw data file would appear as a mass of letters, numbers, and symbols, but by knowing the format and structure of how that data is stored, users can display the data as records, fields, attributes, and elements with specific rules and properties (i.e., some fields are locked or the data is displayed a certain way). A metadata file provides this knowledge.
