What does the term 'attribute' refer to in a database?

1. A specific entry in a data table

2. A characteristic or quality labeling a column

3. A group of data points

4. A summary of data rows

The correct answer is: A characteristic or quality labeling a column

In the context of a database, the term "attribute" specifically refers to a characteristic or quality that labels a column in a data table. Each attribute defines a particular piece of information that is collected for each record in a table. For example, in a database table that contains information about customers, attributes could include "Customer ID," "Name," "Email," and "Phone Number." These attributes help to organize and categorize the data, allowing users to retrieve and analyze specific information about each entry. The other options relate to database concepts but do not accurately define what an attribute is. A specific entry in a data table signifies a particular record, while a group of data points refers to a collection of values that can occur in various contexts but does not define the individual characteristics of those values. Lastly, a summary of data rows can pertain to aggregated information such as totals or averages, which is distinct from the individual attributes that describe the content of those rows.
