As long as a field or data table, added via the Data Model pane, remains empty, it can be
edited (renamed, deleted etc.) via the contextual menu.
Fields in a Data Model that are actually used in the extraction workflow cannot be edited via the
Data Model pane. They are related to a step in the extraction workflow and are edited via the
Step properties pane instead.
The order of the fields can also not be changed via the Data Model pane. It is the Extract step
that determines the order in which data are extracted, so the order of the fields has to be
changed per Extract step.
To learn how to edit fields and change their order, see "Fields" on page218.
Using the Data Model
The Data Model is what enables you to create personalized templates in the Designer module.
You can drag & drop fields from the Data Model into the template that you are creating (see
"Variable Data" on page702). For this, you have to have a template and a data mapping
configuration open at the same time, or import a Data Model (see "Importing/exporting a Data
Model" on the previous page).
The Data Model is reusable, meaning that it can be shared amongst different template layouts
and output types.
Different data mapping configurations could use the same Data Model, allowing a template to
be populated with data from different sources and formats, without the need to modify the
template (see "Importing/exporting a Data Model" on the previous page).
In Workflow, when a data mapping configuration is used to extract data from a data source
(see "Data mapping configurations" on page154), the extracted data is stored in a record set
that is structured according to the Data Model.
Adding fields and data via Workflow
The Data Model is not extensible outside of the DataMapper. When it is used in Workflow - as
part of a data mapping configuration - the contents of its fields can be updated but not its
structure.
There are a number of instances however, where fields may need to be added to the data
model after the initial data mapping operation has been performed. For instance, you might
need to add a cleansed postal address next to the original address, or retrieve a value from a
database and add it to the record.
