Which of the following corresponds to a column that contains descriptive information?

Question

BlackTom AI · Accepted Answer

The question asks which option corresponds to a column that contains descriptive information. 
Option 1: 'record' — A record typically refers to a row in a table, which holds a set of fields for a single entity. It is not the descriptive container of a column itself, so this is not correct for describing a column.
Option 2: 'field' — A field is the column in a table that stores data for a particular attribute. When we say a column contains descriptive information, we’re describing the data stored within that column, i.e., the field. This aligns with standard data modeling terminology.
Option 3: 'data point' — A data point is usually a single value within a field, not the column itself. It describes a value, not the entire column that holds many such values.
Option 4: 'primary key' — A primary key is a special kind of field used to uniquely identify records in a table. While it is a field, the term describes its role/constraint, not the general concept of a column that contains descriptive information. In this context, it is too specific and not the generic descriptor for a descriptive column.
In summary, the column that stores descriptive information for a given attribute is best identified as a 'field', while the other options refer to rows, individual values, or a specific kind of field with a unique constraint. Therefore, the most accurate choice is the field.
