Data Governance > Managing data models

In this example, you create a data model to determine the structure of the data to be managed in the CRM Data Deduplication campaign which you create to allow data stewards to merge duplicate customer data stored in the enterprise CRM.

Talend Data Stewardship has data model awareness which makes possible the syntactic and semantic validation of data. You can define the attributes in the data model and select their types out of a predefined standard or semantic types.

Procedure

  1. In the home page, click DATA MODELS > ADD DATA MODEL.
  2. Enter a name and a description for the new model.
  3. In the Attributes section, define the columns you want to have in the data model as the following:
    1. In the IDENTIFIER field, enter the technical identifier for the first column.
    2. Enter a name and a description for the column in the corresponding fields, if needed.
      What you set in the NAME field is the name displayed in the task list. If no name is set, the technical identifier will be displayed.
    3. From the attribute type list, select the type of the column.
      Standard and semantic types are integrated in Talend Data Stewardship by default
      • For standard types, additional fields are displayed or hidden according to the type you select. These fields are optional and they enable you to define some constraints on the attribute you define such as defining a minimum and/or maximum length or defining a pattern against which to validate the attribute.
      • For semantic types, you can use the Talend Dictionary Service to manage the semantic types. However, the availability of this service depends on the license you have.
  4. Optionally, click the switch next to ALLOW EMPTY VALUES to disable the load of empty fields to Talend Data Stewardship. This option is enabled by default.
  5. Click ADD ATTRIBUTE in the left panel and repeat the above steps to create all the columns you need in the data model.
    The columns defined for the CRM Data Deduplication campaign include information about the customers and the company in which they work as shown in the capture.
