Abstract
A dynamic database structuring method includes the steps of (a) clustering transition probabilities among transactions by on-line, (b) forming a hyper graph representing the transition probabilities of the transactions clustered in the step (a) using weighting, (c) partitioning the hyper graph to obtain clustering information related to objects or records to be stored in a storage, and (d) reorganizing a database by rearranging data in the storage by on-line using the clustering information obtained in the step (c), thereby restructuring the database dynamically.
