Steps

In the DataMapper, steps are part of an extraction workflow (see Data mapping workflow). They contain a specific instruction for the DataMapper, for example to extract data, create a loop, or apply a condition. Some types of steps contain other steps.

Steps are executed sequentially, from top to bottom in an extraction workflow.
Inside a Condition step, some steps may be skipped altogether when they are on a particular branch, whereas in a Repeat step - a loop - several steps may be repeated a number of times.

The Preprocessor and Postprocessor steps are special in that the first can be used to modify the incoming data prior to executing the rest of the extraction workflow while the latter can be used to further process the resulting record set after the entire extraction workflow has been executed.

Step types

These are the types of steps that can be added to a data mapping workflow:

• Preprocessor step
• Extract step
• Repeat step
• Goto step
• Condition step
• Multiple Conditions step
• Action step
• Postprocessor step
