Creating a Logical Data Object Mapping

You can create a logical data object mapping to link data from a physical data object to a logical data object and transform the data.

In the

Object Explorer

view, double-click the logical data object that you want to add the mapping to.

The logical data object editor opens.

On the

Overview

tab in the General area, click

Add

to add a read mapping or a write mapping.

The following image shows the

Add

button:

Enter a name for the mapping, and then click

Finish

The editor displays the logical data object as the mapping input or output, based on whether the mapping is a read or write mapping.

Link data from a physical data object to the logical data object.

Click the

Read Mapping

Write Mapping

tab to edit the mapping.

The mapping editor palette opens.

In the

Object Explorer

view, browse to the physical data object you want to link, and drag the physical data object into the mapping editor palette.

The

Add to Mapping

dialog box opens.

Choose to create a read mapping, write mapping, or lookup mapping.

If you chose to create a read mapping, designate the object access of the read mapping as a related data object or as an independent data object.

Click

The following image shows the result after a user drags the

customer

flat file data object to the mapping editor palette and designates it a read mapping.

Optionally, add a reusable object to the mapping.

You can add a logical data object or other Model repository object.

Right-click in the mapping editor and select

Add Reusable Object

Select one of the objects from the Model repository, and click

Choose to designate the reusable object a Read mapping, Write mapping, or Lookup mapping.

If you chose to designate the reusable object a Read mapping, designate the object access of the Read mapping as a related data object or as an independent data object.

Click

Optionally, add additional objects and transformations to the mapping, and create links between mapping objects, then click the

Data Viewer

view and run the mapping.

Results appear in the

Output

section.
