An Eclipse Modeling Framework (EMF) data source consists of one
or more instance models or metamodels, or a combination of them. To create
a data source, you configure connections to these instance models and metamodels.
Before you begin
Data sources are associated with report designs, which are files
that have RPTDESIGN as a file name extension. You must have
a report design before you start this task. To create a new report design,
see the related task named "Creating report designs for EMF and UML model
information reports."
The EMF data source allows report designs to access
data from EMF models.
About this task
To create an EMF data source:
Procedure
- Open the Data Explorer view: Click .
- In the Report Explorer view, right-click a report design; then
click Open.
- In the Data Explorer view, right-click Data Sources;
then click New Data Source.
- Select EMF Data Source as the data source
type, type a name for the data source, and click Next.
- Specify at least one source to use. You can specify
one or more model instances, one or more metamodels, or a combination of both.
To specify sources, complete the following steps:
- To include an EMF instance model as the source for report data,
click the first Add button, and load the URI for the
instance model.
- To specify a metamodel as the schema for your data, click the
second Add button, and load the metamodel.
- To verify that you entered the source information correctly and
that the sources are accessible, click Test Connection and,
after the test succeeds, click OK.
- Click Finish.
What to do next
You can now use this data source as the basis for an EMF data set.
