Latest Patents

Mariano holds a patent titled "Database query optimization using clustering data mining." This patent describes a method and system for optimizing a database query. The process involves receiving and scanning a database table populated with data. It includes determining statistics and single column histograms associated with the table's columns. The estimated cardinality is based on these statistics and histograms. The invention also identifies all possible correlations among multiple columns by performing clustering data mining, which partitions the data into clusters. Top-ranked columns based on these correlations are determined. The difference between the estimated cardinality and a support count of a cluster is assessed to exceed a threshold. In response, multiple column histograms based on the top-ranked columns are generated. Finally, an optimal query plan is created based on these multiple column histograms.
