What do the term 'Fields' in a table refer to?

• A. Names and data types and properties
• B. Primary keys only
• C. Tables themselves
• D. Queries

Answer: (A)

Fields are the columns of a table—the individual attributes that describe what data is stored in each row. Each field has a name (the attribute’s label), a data type (what kind of value it can hold, like text, number, or date), and properties or constraints (rules such as NOT NULL, DEFAULT, UNIQUE, or foreign key relationships) that govern how data in that column behaves. This combination of name, data type, and constraints is why fields are described as the columns with their attributes. They’re not limited to keys (there can be many non-key fields), they aren’t the tables themselves, and they aren’t queries. For example, in an employees table you might have fields like EmployeeID (integer, primary key, not null), LastName (text, not null), HireDate (date), and Salary (decimal with constraints).
