Lift/Drop tab
The Lift/Drop tab of the Match Analysis tool displays duplicate and unique record counts in a bar chart for the selected baseline and, optionally, comparison results. Lift is the increase in the number of duplicate records. Drop is the decrease in the number of duplicate records. Unique records are shown in yellow and duplicate records are shown in green.
If only a baseline job is selected, the chart will show the results for that one job:
If both a baseline and a comparison job are selected, a chart for the baseline and comparison jobs are shown side by side:
Match Rules tab
The Match Rules tab of the Match Analysis tool displays the match rules used for a single match result or the changes made to the match rules when comparing two match results.
Match rules are displayed in a hierarchical structure similar to how they are displayed in the stage in which they were created. The rule hierarchy contains two nodes: Options and Rules. The Options node shows the stage settings for the selected match result. The Rules node shows the match rules for the selected match result.
To view rule details, select a node in the hierarchy.
If you are comparing match rules between multiple jobs, differences between the baseline and comparison match results are color coded as follows:
- Blue
- Indicates that the match rule in the comparison match result was modified.
- Green
- Indicates that the match rule in the comparison match result was added.
- Red
- Indicates that the match rule in the comparison match result was omitted.
This is demonstrated in this figure.
