    Graphical results in chart and pie chart showing the statistics of the duplicate records and groups.
    In this view, the charts give a global picture about the duplicates in the analyzed data. In the first tables, you can read statistics about the count of processed records, distinct records with only one occurrence, duplicate records (matched records) and suspect records that did not match the rule. Duplicate records represent the records that matched with a good score - above the confidence threshold. One record of the matched pair is a duplicate that should be discarded and the other is the survivor record.
    In the second table, you can read statistics about the number of groups and the number of records in each group. You can click any column header in the table to sort the results accordingly.
