Once you have defined a match rule and then attached the match rule to a specific entity of a data model in Talend Studio, you can check whether the match rule works well from Talend MDM Web User Interface.
In the Staging Area, you are allowed to perform a series of integrated matching tasks which can group together similar records in order to create a "golden" record, that is, a consolidated version of all the records in the group.
In this scenario, the following tasks will be verified:
A staging area validation task will be performed on the staging data records pending validation.
Similar staging data records that belong to the same entity will be matched according to the criteria you have defined in the match rule.
If two or more data records are similar enough, they will be merged into a golden record.
A task will be created in Talend Data Stewardship Console for the golden record.
The golden record will be written into the master database.
For more information about the integrated matching process and the tasks involved in the process, see Talend MDM Web User Interface User Guide.
