Data Elements retrieve data from source objects and standardize it for use in matchers and match code generators.
The Data Elements flipper of a decision table defines the initial input data for the match criteria. The output of a data element is used by the selected Matchers (as defined in the Match Criteria Matchers topic here). The data elements required are determined by the kind of data being matched, for example, the following image shows data elements for matching on individuals.
A data element retrieves the data required for comparison during matching. This often involves the reduction (or 'normalizing') of data to a matchable form, like making letters lower case in a text string, removing spaces from phone numbers, or expanding abbreviations. Some data elements retrieve data for matching without normalizing.
Data elements can be chained so that the output of one data element can be used as input to another data element. Examples are included in the Chaining Match Expressions to Expand Functionality section of the Matching Algorithms and Match Expressions topic here.
