Inputs to the Two-source Match stage
The Two-source Match stage takes four input sources. The data and reference sources can be from any parallel database, file, or processing stage.
The four inputs to the Two-source Match stage come from the following
sources.
- Data source
- Reference source
- Frequency information about the data and reference source, generated by the Match Frequency stage. You can input frequency data from the Match Frequency stage as a part of the current job. You can also input frequency data that was output from a Match Frequency job that was run previously.
When you configure the stage, designate an existing two-source match specification from the assets based on the column definitions of the data and reference sources.
The Two-source Match stage matches and groups your input data based on the match specification. You select which columns to output.
