MODAL_EXACT

The MODAL_EXACT rule selects the row that has the highest number of columns with the most frequent non-blank values.

The following table displays a sample cluster and indicates the preferred record for the cluster based on the MODAL_EXACT rule:

Cluster ID	Employee Name	City	Age	Department	Comment
1	John Smith	New York	31	Sales	Row-level preferred record
1	J Smith	New York	31	Human Resources
1	John Smith	Seattle	30	Sales

The MODAL_EXACT rule selects the first row as the preferred record because it has four columns with the most frequent non-blank values.

Use the following format to configure a MODAL_EXACT rule:

<RowRules>   
   <RowRule name="<Rule name>" rule="MODAL_EXACT" order="<Execution order>">
   </RowRule>   
</RowRules>

The format uses the following parameters:

Rule name: Unique name for the rule.
Execution order: Optional. Order of execution for the rule. Use an integer value for the order of execution. If you do not specify the execution order, the consolidation process runs the rule based on the sequence of rules listed in the consolidation rules file. If you specify the execution order for a rule, you must specify the execution order for other rules.

The following sample uses the MODAL_EXACT rule:

<RowRules>
   <RowRule name="rowlevel7" rule="MODAL_EXACT" order="1" />
</RowRuless>
