In this example, you create a data model to determine the structure of the data
to be managed in the Reconciling client data campaign which
allows data stewards to merge redundant client data coming from different
systems.
Talend Data Stewardship
has data model awareness which makes syntactic and semantic validation of data
possible. Therefore, a campaign relies on a data model to ensure that the data
matches the expected structure and format.
By defining the structure of data for this Merging campaign, you
define the attributes in the data model and select their types out of a predefined
standard or semantic types.
Before you begin
-
An administrator has created Talend Data Stewardship users and assigned them roles in Talend Administration Center. For further information, see Creating Data Stewardship users.
-
You have been assigned a campaign owner role in Talend Administration Center.
Procedure
-
Log in to Talend Data Stewardship.
-
Select .
-
Enter a name and a description for the new model in the
Name and Description fields
respectively.
Optional fields are marked as optional next to their
names
-
In the Attributes section, define the columns you want
to have in the data model as the following:
-
In the IDENTIFIER field, enter the technical
identifier for the first column.
-
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.
-
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 Talend Dictionary Service to manage the
semantic types. However, the availability of this service depends on
the license you have.
-
Click the switch next to DEFINE LIST OF VALUES to
display fields where you can set specific values for the attribute.
Any values that are not in this list are marked as invalid in the task
list.
-
Click the switch next to ALLOW EMPTY VALUES to disable
the load of empty fields to Talend Data Stewardship, if needed. This
option is enabled by default.
-
Click ADD ATTRIBUTE in the left panel and repeat the
above steps to create all the columns you need in the data model.
