Element Simple Group Classify Operation

Classifies groups of records with roles representing overall data quality of the groups. For additional information, see Simple Group Classifier.

Name	Type	Required	Description
Group Id Column	String	Yes	Column or expression that contains group identifiers (groupId) for each record.
Role Column	String	Yes	Column that stores group quality.
Column Sets	List of Column Set	No	Rule list for group evaluation. Group quality is evaluated by the first columnSet member with a satisfying condition (the "when" property).
Already Grouped	Boolean	Yes	Informs the process that the input record flow is already grouped by a used groupId and so it's unnecessary to group it again. The switch is usable in the common case that the group classifier follows a unification step and its groupId corresponds to the unification's candidate or client group ids. Default value: false.
Default Locale	String	No

Detailed Description of Unification Extended

This step works with groups of records usually acquired from the Unification process. Utilizing predefined rules, which compare members of the same group, the overall group quality can be evaluated. Groups are defined by the value in groupIdColumn. If this value is empty (null), the record in question defines its own single member group with a group role of 'C'.

U - single member group of A quality.
A - best quality group (records can be automatically assigned to a single entity).
M - minor differences in group (recommended for manual control).
C - major differences in group or empty group id (recommended for manual control and correction).

The following group qualities are defined:
