You can combine the work of several groups in your enterprise that
have mapped relationships by using the function to combine mapping models.
Before you begin
Prerequisite:You must have at least two mapping models in
the current Data Project Explorer view.
About this task
You can transform a series of relationships by combining mapping
models from multiple mappings to one mapping, or from sequentially created
mapping models to another mapping model.
To combine mapping models:
- In the Data Project Explorer view, expand the data design project
that you want to work with.
- Select Mappings.
- Right-click on a mapping model that you want to use as
the model that you combine other models with.
- Select Combine Mapping to open the Combine
Two Mapping Models window. The mapping type depends on the content
of the mapping model that you selected. For example,
Combine Parallel Mapping Models |
You combine mapping models in parallel when you create multiple mapping
models that might contain different sources but use the same target. You combine
two of these mapping models to merge information into a third mapping model. |
Combine Sequential Mapping Models |
You combine mapping models in a sequential order when you create
a mapping model with a source and a target, and then use that target as the
source for a second mapping model. This action creates a third mapping model
that contains the source of the first mapping model and the target of the
second mapping model. |
- In the Combine with group box, specify a
mapping model to combine with the mapping model that you selected in step 3.
- In the Resulting mapping model group box,
specify a file name for the new mapping model.
- Click OK.
Results
Each group box contains source and target information that is related
to the selected mapping model. The new mapping model that is a combination
of two other mapping models is added to the data design project in the Data
Project Explorer view and saved in the current workspace.
