Which of the following names is not used for table rows in data mining terminology?

• A. Rows
• B. Tuples
• C. Attributes
• D. Records

Answer: (C)

In data mining and database terms, a single row is a record of one observation and is often called a row, a tuple, or a record. The things describing that observation—the columns in the table—are the attributes (also known as features or fields). Since attributes refer to the properties that define the data, they do not name the individual row. So the term that is not used for table rows is Attributes.
