Data Flows (DMM)

A data flow conveys data between steps in a data transformation diagram.

In the following example, data flows convey data from the Acme database input through several actions, and to the Giant Corp database output:

When you link two steps with a data flow, the data structure of the destination object is initialized with the data structure of the source object.

Any name, code or data type changes you perform on the data structure columns of a source object are automatically applied to the data structure columns of the target object, when they match.

• Creating a Data Flow
  You can create a data flow from the Toolbox or Model menu.
• Data Flow Properties
  To view or edit a data flow's properties, double-click its diagram symbol or Browser or list entry. The property sheet tabs and fields listed here are those available by default, before any customization of the interface by you or an administrator.
