Automated mining of granular database scheme
S. K. M. Wong, Dan Wu · 2003
We introduce an algorithm for automatic mining of data dependencies in a relation. The mined data dependencies can be used to construct a granular database scheme. Unlike the traditional approach, the granular database scheme has the following advantages: (1) it is able to present a coarse or refined view of the relations in the database; (2) queries can be answered more efficiently using the granular database scheme than the flat database scheme.
