It is often necessary to use reference data with certain steps (for example, to look up values for matching purposes). The reference data must be placed in dictionary files, which are created and maintained in iWay Data Quality Center (DQC).

The process for creating dictionary files involves:

• Reading the reference data from a supported input type (text file, DBF file, or JDBC).
• Preparing the data (for example, creating a matching value with the Create Matching Value step).
• Generating the dictionary file using the appropriate generator.
