Quizplus · Accepted Answer

Affinity patterns occur when two or more database elements tend to occur together in a significant way. They can be identified through unsupervised data mining techniques such as clustering or association analysis. Option A is incorrect because affinity patterns help identify database elements that are similar, not different. Option C is incorrect because affinity patterns can be identified through unsupervised data mining as well. Option D is incorrect because affinity patterns can occur with two or more elements, not necessarily three or more.
