Notas
SQL Server query optimization relies, in part, on data distribution statistics maintained on indexes. To aid query optimization, SQL Server can generate data distribution statistics for one or more columns in a table without imposing overhead associated with index maintenance. SQL Distributed Management Objects (SQL-DMO) implements data distribution statistics creation using the Index object and the StatisticsIndex property.
