In database systems, metadata refers to data that provides information about other data. Specifically, it describes the structure, organization, and characteristics of data stored within the system. This includes details such as table names, column names, data types, constraints, and relationships between tables.

While Pname is an example of a bad variable/field name, I don't think that means that the table is badly designed. However, field names are an example of metadata (i.e. data about data).

The correct answer is: E. Poor table design he name "Pname" is unclear and doesn’t explicitly indicate it’s storing a "Family Name" or "Person Name.

While "Pname" might not be the most descriptive column name, labeling it as "poor table design" is subjective and doesn't accurately categorize it.

But the clarity or quality of the name affects data understanding and data quality, but not its classification as metadata.
