Campaign owners can update data models whether they are attached to campaigns or not.

When updating a data model used by one or more campaigns, the campaigns are updated as follows:

  • Campaigns are temporarily disabled,
  • Campaign metadata is updated,
  • Tasks are updated, attributes are renamed and the tasks are revalidated,
  • Campaigns are enabled.

Before you begin

The data model has been defined in Talend Data Stewardship.

Procedure

  1. Log in to Talend Data Stewardship as a campaign owner.
  2. Select DATA MODELS and click the name of the data model you want to open.
    Campaigns which use the data model are temporarily disabled.
  3. Modify the data model metadata or attribute definition, maximum/minimum value or the pattern used on the attribute.
    You can also add new attributes to the data model. However, when you change an attribute identifier, you need to modify accordingly the Talend Job you use to communicate with the campaign and write, read or delete tasks.
  4. Click EDIT DATA MODEL at the bottom of the page.
    Campaign metadata is updated, attributes are renamed and the tasks listed in the campaign which are not resolved yet are updated and revalidated. Also, an entry is added to the history of each of the tasks to show the changes done in the data model.

Results

The data model is updated according to the modifications done and the campaigns using the data model are enabled.
