摘要：A decision tree can be used for clustering of frequently used attributes to improve tuple reconstruction time in column-stores databases. Due to ad-hoc nature of queries, strongly correlative attributes are grouped together using a decision tree to share a common minimum support probability distribution. At the same time in order to predict the cluster for unseen attribute set, the decision tree may work as a classifier. In this paper we propose classification and clustering of unseen attribute set using decision tree to improve tuple reconstruction time
