Quizplus · Accepted Answer

In a well-structured relational database, every column in a row should have only one value. This is known as the atomicity property, which helps to ensure data integrity and eliminate data redundancy. The other choices are incorrect as foreign keys can be null, there is no requirement for a minimum number of foreign keys, and all tables need not be related to each other.
