When discussing structured databases, data analysts refer to the data contained in a row as a record. How do they refer to the data contained in a column?

• A. Column
• B. Field
• C. Attribute
• D. Entry

Answer: (B)

In a structured database table, a row is a record that holds all the values for one entity, and a column represents a single attribute of that entity. The data contained in a column are the actual values for that attribute across all records, and each individual value at the intersection of a row and that column is called a field. For example, a column labeled "Email" holds each employee’s email address, and each email address is a field. The term attribute refers to the column’s meaning (the property being described), not to the data item itself, and entry isn’t the standard term used here. So the data contained in a column are called fields.
