degree of uniqueness of one or more columns of a table.

b) Combination of Uniqueness and Non Uniqueness Profiling:-



1) In the first run , the columns like :-Address, City, Combined_Names,Company_Name, Country were selected among the list of complete set of columns.That yielded cent percent uniqueness.In that case, the combination of the records and its repetition are checked across the entire table. to be more specific:-

Mr.James Butt Benton, John B Jr 6649 N Blue Gum St New Orleans Orleans

This row of data, should have an identical presence at multiple places in the table, then only presence of duplicate records are counted.Else the results are unique.

  2) The “Duplicate Count” appears only if the the selected combination of column fields are repeated across the table.

The Number Of Runs of the Profiling:-

All the profiling could be run multiple times. We can choose different columns at each time of run of the profiling. Different runs of the same profiling will be displayed as highlighted.
