Create maps to specify sources and targets

About this task

After defining data objects and their properties in the Type Designer, define the map in the Map Designer where you specify the source of the input and the target of the output. Sources and targets are specified with map cards. Each map can have none or more input cards, and one or more output cards.

To create maps in the Transformation Extender Development perspective:


  1. Create a map source file. The file name extension of map source files is .mms.
  2. Create required executable map(s) in the map source file (.mms).
  3. Create an input card that represents your input data.
  4. Create an output card that represents your desired output.
  5. In the output card map rules, specify the logic necessary to transform the input data to the desired output data.
  6. Build the map. This creates a compiled map file (.mmc).
  7. Run the map.
