STATISTICS ,[object Object],[object Object],[object Object],[object Object],Statistics will provide, how many values the column has, as well as the sum, minimum, mean, maximum, and standard deviation of those values. A histogram is also provided showing how the column's values are distributed. Statistics are calculated for all numeric columns in the table.

JOIN – FROM TABLES ,[object Object],[object Object],[object Object],[object Object],Joining involves appending fields (items) of one table to those of another through an attributes or field common to both tables.
