Creating a Logical Data Object Mapping

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.
  1. 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.
  2. 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:
  3. 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.
  4. Link data from a physical data object to the logical data object.
    1. Click the
      Read Mapping
       or
      Write Mapping
       tab to edit the mapping.
      The mapping editor palette opens.
    2. 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.
    3. Choose to create a read mapping, write mapping, or lookup mapping.
    4. 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.
    5. Click
      OK
      .
    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.
  5. Optionally, add a reusable object to the mapping.
    You can add a logical data object or other Model repository object.
    1. Right-click in the mapping editor and select
      Add Reusable Object
      .
    2. Select one of the objects from the Model repository, and click
      OK
      .
    3. Choose to designate the reusable object a Read mapping, Write mapping, or Lookup mapping.
    4. 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.
    5. Click
      OK
      .
  6. 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.
