Metadata = “data about data.”
In this case, Pname is the column name (a label describing the stored data).
The actual family names (e.g., Khan, Smith, Wong) would be the data itself.
So:
Column name (Pname) → Metadata
Stored value (e.g., “Smith”) → Data
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.
But the clarity or quality of the name affects data understanding and data quality, but not its classification as metadata.
