This scenario describes a six-component Job that aims at:
matching each processed group number in the grp column against the entries that have exactly the same values in the reference input file,
checking the edit distance between the entries in the firstname column of an input file against those of the reference input file.
The outputs of these two matching types are written in three output files: the first for match values, the second for possible match values and the third for the values for which there are no matches in the lookup file.
In this scenario, we have already stored the main and reference input schemas in the Repository. For more information about storing schema metadata in the Repository, see Talend Studio User Guide.
The main input file contains four columns: grp, gender, firstname and count. The data in this input file have problems such as duplication, first names spelled differently or wrongly, different information for the same customer.
