What is referred to as the heading for each column in a database?

The correct term for the heading for each column in a database is known as the field name. In database terminology, a field name represents a specific attribute or characteristic of the data stored in that column. For example, in a database of employees, field names might include "First Name," "Last Name," "Employee ID," and so on.

Field names are crucial because they provide context for the data, making it easier to understand what each column represents and allowing users to interact with the data more effectively. They serve as labels that describe the data type or information contained in that column, facilitating data management and retrieval tasks.

The other options do not accurately describe the headings for database columns. A figure typically refers to numerical data or a graphical representation, while a file is a collection of data or information stored under a single name, and a folder is a digital space for organizing multiple files. Thus, none of these alternatives serve the specific purpose of denoting the headings for columns within a database structure.
