Each attribute contains a certain number of distinct data values. A value recode is a user-defined revision or recoding of a distinct data value which modifies or replaces the original value.

Recoded values are useful, for example, if you are standardizing the way your company enters phone numbers into a database or the way you enter data for customer addresses and postal codes. With value recoding you can apply global changes to data formats and structures, and be assured that the resulting data values are consistent in their format and presentation. The Quality Transformer process can use tables of recoded values to standardize and clean data.

Each record in a recode table contains two columns:

  • original value
  • new value

To recode values

  1. In the Navigation View, click the Discover bar, and click the Entities tab.
  2. Expand the entity that contains the attribute with which you want to work.
  3. Right-click the attribute and select Drill down to metadata. (You can also open the attribute's Summary Data View, and click Attribute Metadata.)

    The List View of attribute metadata displays.

  4. Double-click the row of Values metadata.

    The Values List View displays.

  5. Select rows that contain the Values you want to recode.
  6. Right-click the selection and select Recode values.

    The Recode Values window opens, displaying a list of values selected for recode.

  7. Specify the new value to use for the recode.
  8. Click OK.

    Two new columns are added to the attribute's metadata:

    • Value Recode. Displays the value recodes. If the value has not been recoded, the original value is shown.
    • Value Recoded? If the value in the Value Recode column is a recode, this column will display Yes, otherwise it is blank.
    Note: To export value recode look-up tables to use in the Quality Transformer process, see Generating Recode Value Look-Up Tables.
