This compares all columns from Table1 against all columns for Table2.
If matches are found for rows then they are counted for both.
This is designed to help search for possible primary keys between two database tables.
The higher the number the more matches have been found and the more likely it is to be related.
Note that small numbers and dates may be misleading.
Columns with no matches are not included in the results.
Datatypes between string/number don't see to matter.
